1. Compression Springs:
Compression Springs are open-coil helical springs that offer resistance to a compressive force applied axially. Helical compression springs are used to resist applied compression forces or to store energy in a push mode. Compression springs have the most common configuration and are most commonly used in engineering, tools, automotives, aerospace and consumer applications. Most compression springs are straight cylindrical springs made out of round wire.

Compression Spring Types:
Compression springs from a manufacturer come in a variety of types including: Conical, Barrel, Hourglass and Cylindrical shapes.
Wire Selection: round, square or special-section, round being the most adaptable.
• Compression Spring Mandatory Specification: the functional design characteristics.
• Compression Spring Secondary Specification: which is useful for reference and been considered as advisory data.
• Dimensional Limits: governed by the pitch allotted with regard to allowable solid height and outer and inner diameters.
Stress Level: Determined by the dimensional limits together with the load and deflection requirements. Our compression springs are stress-relieved to remove residual bending stresses produced by the coiling operation.
Compression Spring Stress Levels
• A compression spring can be compressed into solid without a permanent set, so that an extra operation for removing the set is not needed. These springs are designed with torsional stress levels when compressed into solid that do not exceed above 40 percent of the minimum tensile strength of the material.
• A compression spring can be compressed into solid without further permanent set after the set is initially removed. These may be pre-set by the spring manufacturer as an added operation, or they may be pre-set later by the user prior to or during the assembly operation. These are springs designed with torsional stress levels when compressed to solid that do not exceed 60 percent of the minimum tensile strength of the material.
• Springs, which cannot be compressed into solid without some further permanent set-taking place is because set cannot be completely removed in advance. These springs involve torsional stress levels, which exceed 60 percent of the minimum tensile strength of the material. The spring manufacturer usually advise the user of the maximum allowable spring deflection without set whenever springs are specified in this category.
Remember: It is extremely important to consider carefully the space allotted to insure that the compression spring would function properly to begin with, thereby avoiding expensive design changes

2. Tension Springs:
Tension springs are stressed in shear but are “pulled” rather than “pushed”, in order to effect energy transfer. By virtue of this they have different end forms to anchor them and to effect the actuation of the energy stored. The form of the ends is varied and virtually infinite in shape to suit the user and the application. However there are a number of standard or commonly used shapes. Tension springs are usually close coiled. They have a nominally linear rate, when close coiled they are coiled with “initial tension"

Generic non-linear flow characteristics of the conventional ball valve limit the applications of flow modulation in fluid processes. This work presents the flow characteristics of fluid flowing through the conventional and modified ball valves for feasibility of a “linear” ball valve. Theoretical studies are discussed for determining explicit and implicit factors on the valve coefficient, which modulates the flow rate of fluid when the ball valve is operated in flow control processes. In experiment, the cross-sectional opening area at various opening degrees, the shape, and the location of the hole passage in valve ball are examined for complicated relations dependent to the flow rate of fluid. It can be concluded that those factors cause the modulation of flow rate when the ball is turned at different opening degree.

In extended design of flow characteristics for linearity, flow control valves have been used in a wide range of applications in fluid processes. Typically, the term “valve” applies to a variety of devices for controlling the flow of fluid. Various valves allow for on-off control, modulation of the flow rate through the system, prevention of back flow, pressure relief as a safety device. A combination of a valve and a manual / automatic. Ball Valves (Two, Three, Four Way Ball Valves), Automation Series Ball Valves, Fire Safe Ball Valves, Globe Valves, Gate Valves, Check Valves, Butterfly Valves, Diaphragm Valves, Pinch Valves, Forged Steel Valves, Sight Glass, Strainers,

BALL VALVES:
Ball valves offer very good shut-off capabilities. A simple quarter-turn (90°) completely opens or closes the valve. This characteristic minimizes valve operation time and decreases the likelihood of leakage due to wear from the gland seal. Ball valves can be divided into two categories: reduced bore and full bore. In reduced bore valves, the valve opening is smaller than the diameter of the piping; in full bore valves, the valve opening is the same size as the diameter of the piping. Full bore ball valves are often valued because they minimize the pressure drop across the valve.

BUTTERFLY VALVES:
Butterfly valves are characterized by their simple construction, lightness in weight, and compact design. Their face-to-face dimension is often extremely small, making the pressure drop across a butterfly valve much smaller than globe valves (see below). Materials used for the valving element and sealing can limit their applications at higher temperatures or with certain types of fluids. Butterfly valves are often used on applications for water and air, and in applications with large pipe diameters.

GATE VALVES:
The construction of a gate valve is similar to that of a floodgate: flow is controlled by raising or lowering the valving element, which is generally available in three different types: solid (plain), flexible, and split. The latter two types help prevent the valving element and body from being deformed due to various operating conditions. Like Ball valves, gate valves are not usually used to regulate flow. One of the reasons for this is because the valving element can be damaged when in the partially open position. Similarly, they also limit the pressure drop across the valve when fully open. However, setting the valve to the fully open or closed position requires the handle to be turned many times, which generally makes these valves have the longest operating times among those valve types,

GLOBE VALVES:
The globe valve is suitable for use on a wide variety of applications, from flow rate control to open/close operation. In this type of valve, flow rate control is determined not by the size of the opening in the valve seat, but rather by the lift of the valve plug (the distance the valve plug is from the valve seat). One feature of globe valves is that even if used in the partially open position, there is less risk of damage to the valve seat or valve plug by the fluid than with other types of manual valves. Among the various configurations available, needle type globe valves are particularly well suited for flow rate control.

DIAPHRAGM VALVES:
Diaphragm valves use a 'pinching' method to stop the valve flow using a flexible diaphragm. They are available in two types: weir and straight-way. The most commonly seen of the two is the weir-type. This is because the straight-way type requires additional stretching of the diaphragm, which can shorten the diaphragm's life-span. One of the major advantages of using diaphragm valves is that the valve components can be isolated from the process fluid. Similarly, this construction helps prevent leakage of the fluid without the use of a gland seal (packing) as seen in other types of valves. One the other hand, the diaphragm becomes worn more easily and regular maintenance is necessary if the valve is used on a regular basis. These types of valves are generally not suited for very high temperature fluids and are mainly used on liquid systems

CHECK VALVES:
Check Valves [NRV] are Swing Type and Bolted cover Construction. The one piece disc construction is securely fastened to the hinge by means of a lock nut & pin. The Disc is free to rotating type to avoid any other wear. The hinge pin offers excellent wear resistance properties.Swing Check valves also can be supplied with Titling disc design, Dash pot arrangement and outside lever & weight design for use where control of the disc is desires. Also offer P.T.F.E. (PFA / FEP) Lined Ball Type/Y Type & Rubber Lined Flap Type Check valve for high corrosive use.

 
 


What is VALVE POSITIONER ?
A control valve positioner is a device that sets valves at their correct position. Control valve positioners can be found in external power supplies where they ensure that the opening is as per the control signal. The positioners have a position feedback link which senses the valve opening.
Positioners are used to control the opening or closing of the actuator based on Electric , or pneumatic signals, to amplify the input pneumatic signal. Positioners also be customized the valve positioner on the control valve to regulate the flow of the control valve based on different factors , You can set a specific threshold for these factors.

How do valve positioners work ?
In standard valves, when the valve is given a command to open to a certain point, there is no feedback to verify that the valve has opened to that position, With a valve positioner,

Types Of Positiners:
Pnuematic Valve Positioner:
Pneumatic Positioner which utilizes a unique spool valve, is a cam characterized, force balanced instrument that is simple, rugged, and very user friendly for calibration and maintenance.

- Valve Positioners
- Air-Cylinders , Relays , Clutches , Web Tensioners and Brakes

Transducer is a force balance device in which, when electrical current is passed through the coil of transducer magnetic field is created which acts on the magnet assembly, causing the anvi& diaphragm to move away from or forward the nozzle (flapper nozzle) depending on the direction of current flow. Motion at the nozzle assembly is proportional to the amount of current passing through the coil.

The flapper/anvil move away from or forward towards the nozzle creates back pressure which acts as pilot pressure to an integral booster relay. when input electrical current increases (or decreases for reverse acting) causes proportional output pressure increases.

Zero and Span are calibrated by turning easily accessible adjusting screws on the front face of the unit. The zero adjusting screw causes the nozzle to move relative to the flapper/anvil. The span adjusting screw is a potentiometer that limits the current through the coil. A Thermistor circuit in Series with the coil provides temperature compensation.

I/P Transducers:This is Explosion proof I/P (current to pressure) transducer converts a 4–20mA electrical current signal to a proportionally linear pneumatic output. The unique conversion technology utilizing open loop control provides a high level of accuracy and repeatability for the operation of actuated valves. A low mass control circuit provides consistent output in high vibration applications. This compact unit is housed in an explosion proof enclosure that is designed for pipe, bracket or direct manifold mounting. This explosion-proof and intrinsically safe field device is available with an integral volume booster or as a low-flow signal converter that directly mounts to a pneumatic valve positioner.

Principle of Operation:

The input current flows through the coil thereby magnetizing the soft-iron yoke. The flux lines of this system being exposed at the gap apply a force proportional to the input signal on the permanent magnet which is made from a highly coercive metal

The small magnet together with the flapper forms the moving parts, controlling the air pressure at the nozzle, which is proportional to the magnetic force. The air flowing from the nozzle forms a restoring force balanced by the force applied to the magnet. The nozzle is supplied with air through a throttle. And back pressure through power amplifier gives proportional output. The described units are properly matched, Hance, a linear correspondence of electric input and pneumatic output signals is achieved.

The direction of action of the converter is determined by the coil polarization.

Zero adjustment is made by twisting the tensioning band, on which the flapper is mounted.

Range adjustment is performed using the potentiometer connected with a resistor in parallel to the coil.

A Tool, is any Physical item that can be used to achieve a goal, especially if the item is not consumed in the process.

Tools that are used in particular fields or activities may have different designations such as "instrument", "utensil", "implement", "machine", or "apparatus". The set of tools needed to achieve a goal is "equipment".

HAMMER : A Hammer is a tool meant to deliver an impact to an object. The most common uses for hammers are to drive nails, fit parts, forge metal and break apart objects. Hammers are often designed for a specific purpose, and vary in their shape and structure. The term hammer is also used for some devices that are designed to deliver blows, e.g., the caplock Mechanism of firearms. The hammer is a basic tool of many professions. The usual features are a handle and a head, with most of the weight in the head. The basic design is hand-operated.

ADJUSTABLE SPANNERS: An adjustable wrench or adjustable spanner , is a wrench with a "jaw" of adjustable width, allowing it to be used with different sizes of fastener head (nut, bolt, etc.) rather than just one fastener, as with a conventional fixed spanner. An adjustable spanner may also be called a Bahco (European usage, see below), crescent wrench , adjustable end wrench , wrench, shifter, shifting spanner shifting adjustable, fit-all or adjustable angle-head wrench.

SPANNER OR WRENCH : A wrench (or spanner) is a tool used to provide grip and mechanical advantage in applying torque to turn objects—usually rotary fasteners, such as nuts and bolts, common shapes are called open-ended spanner and ring spanner. Higher quality wrenches are typically made from chromium-vanadium alloy tool steels and are often drop-forged. They are frequently chrome-plated to resist corrosion and ease cleaning.

WRENCHES : The monkey wrench or gas grips is an Adjustable Wrench, is now used only for heavier tasks, having been mostly replaced by the lighter and sleeker shifting adjustable

CLAMP (TOOL): A clamp is a Fastening device to hold or secure objects tightly together to prevent movement or separation through the application of inward Pressure.

PINCERS (TOOL) &PLIERS : Pincers are a hand tool used in many situations where a mechanical advantage is required to pinch, cut or pull an object. Pincers are first-class levers, but differ from pliers in that the concentration of force is either to a point, or to an edge perpendicular to the length of the tool. This allows pincers to be brought close to a surface, as is often required when working with nails , Pincers are a similar tool with a different type of head used for cutting and pulling, rather than squeezing.

PLIERS : Pliers are a hand tool used to hold objects firmly, possibly developed from tongs used to handle hot metal in Bronze Age Europe[1] they are also useful for bending and compressing a wide range of materials. Generally, pliers consist of a pair of metal first-class levers joined at a fulcrum positioned closer to one end of the levers, creating short jaws on one side of the fulcrum, and longer handles on the other side.[1] This arrangement creates a mechanical advantage, allowing the force of the hand's grip to be amplified and focused on an object with precision. The jaws can also be used to manipulate objects too small or unwieldy to be manipulated with the fingers.

CENTRE PUNCH: A Center Punch is used to mark the centre of a point. It is usually used to mark the centre of a hole when drilling holes. A drill bit has the tendency to "wander" if it does not start in a recess. A centre punch forms a large enough dimple to" guide" the tip of the drill bit. When drilling larger holes, and the web of the drill is wider than the indentation produced by a centre punch, the drilling of a pilot hole is usually needed. An automatic centre punch operates without the need for a hammer.

SCREW DRIVER : A Screwdriver is a hand-tool for turning (driving) Screws and sometimes bolts or other machine elements with a mating drive system). A typical screwdriver comprises
- an approximately cylindrical handle of a size and shape to be held by a human hand;
- A nut driver is a tool for tightening nuts and bolts. It essentially consists of a socket attached to a shaft and cylindrical handle and is similar in appearance and use to a screwdriver

TWEEZERS :Tweezers are tools used for picking up objects too small to be easily handled with the human hands. They are probably derived from tongs, pincers, or scissors-like pliers used to grab or hold hot objects since the dawn of recorded history. In a scientific or medical context they are normally referred to as forceps. Tweezers make use of two third-class levers connected at one fixed end (the fulcrum point of each lever), with the pincers at the others.

FILE (TOOL) : A File is a metalworking, woodworking and plastic working tool used to cut fine amounts of material from a work piece. It most commonly refers to the hand tool style, which takes the form of a steel bar with a case hardened surface and a series of sharp, parallel teeth. Most files have a narrow, pointed tang at one end to which a handle can be fitted. A similar tool is the rasp. This is an older form, with simpler teeth. As they have larger clearance between teeth, these are usually used on softer, non-metallic materials. Related tools have been developed with abrasive surfaces, such as diamond abrasives or silicon carbide. Because of their similar form and function, these have also been termed 'files'.

NEEDLE FILES: Needle files are small files that are used in applications where the surface finish takes priority over metal removal rates but they are most suited for smaller work pieces. They are often sold in sets, including different shapes.

DIAMOND FILES :Diamond files have small particles of Industrial diamonds embedded in their surface (or into a softer material that is bonded to the underlying surface of the file). The use of diamonds in this manner allows the file to be used effectively against extremely hard materials, such as stone, glass or very hard metals such as hardened steel or carbide against which a standard steel file is ineffective. Diamond files are also the only type that may be used with a back-and-forth motion without damaging the file. These may also be called diamond laps, as the "teeth" are not regular projections, as in a file, but particles, usually shaped and located randomly and held in place by a softer (any other) material.

HACKSAW: A hacksaw is a fine-tooth hand saw with a blade held under tension in a frame, used for cutting materials such as metal or plastics. Hand-held hacksaws consist of a metal arch with a handle, usually a pistol grip, with pins for attaching a narrow disposable blade. A screw or other mechanism is used to put the thin blade under tension. The blade can be mounted with the teeth facing toward or away from the handle, resulting in cutting action on either the push or pull stroke.On the push stroke, the arch will flex slightly, decreasing the tension on the blade, often resulting in an increased tendency of the blade to buckle and crack. Cutting on the pull stroke increases the blade tension and will result in greater control of the cut and longer blade life.

BLADES : Blades are available in standardized lengths, usually 10 or 12 inches for a standard hand hacksaw. "Junior" hacksaws are half this size. The pitch of the teeth can be anywhere from fourteen to thirty-two teeth per inch (tpi) for a hand blade, hacksaw blades have used high speed steel for their teeth, giving greatly improved cutting and tooth life. Powered hacksaws may use large blades in a range of sizes, or small machines may use the same hand blades.

WOOD HAND SAWS:In Woodworking and carpentry, hand saws, also known as "Panel Saws", "fish saws", are used to cut pieces of wood into different shapes. This is usually done in order tojoin the pieces together and create a wooden object. They usually operate by having a series of sharp points of some substance that is harder than the wood being cut. The hand saw is a bit like a tenonsaw, but with one flat, sharp edge.

MACHINE FILES :A filing machine is similar in appearance to a scroll saw or bandsaw in that the file is mounted vertically in the middle of a table. When in operation the file reciprocates vertically while the work piece is presented to the file's face and manipulated around the table/file as the shape requires. The cone point of the pictured, top two files allows the files to center themselves firmly in the bottom file holder. The pictured, lower two files are required to be inserted into the bottom file holder and physically restrained with set screws, an identical process as for the top holder. Filing machines are useful tools as they reduce fatigue and improve product accuracy, and although not usually seen in modern production environments, they may be found in older toolrooms or diemaking shops as an aid in the manufacture of specialist tooling.





MILLING CUTTER : Milling cutters are cutting tools typically used in milling machines or machining centres to perform milling operations (and occasionally in other machine tools). They remove material by their movement within the machine (e.g., a ball nose mill) or directly from the cutter's shape (e.g., a form tool such as a hobbing cutter).

DRILL BIT : Drill bits are cutting tools used to create cylindrical holes, almost always of circular cross-section. Drill bits come in many sizes and have many uses. Bits are held in a tool called a drill, which rotates them and provides torque and axial force to create the hole. Specialized bits are also available for non-cylindrical-shaped holes. The shank is the part of the drill bit grasped by the chuck of a drill. The cutting edges of the drill bit are at one end, and the shank is at the other. Drill bits come in standard sizes, described in the drill bit sizes article. A comprehensive drill bit and tap size chart lists metric and imperial sized drill bits alongside the required screw tap sizes. The term drill may refer to either a drilling machine or a drill bit for use in a drilling machine. In this article, for clarity, drill bit or bit is used throughout to refer to a bit for use in a drilling machine, and drill refers always to a drilling machine. Titanium nitride (TiN) (sometimes known as “Tinite” or “TiNite” or “TiN”) is an extremely hard ceramicmaterial, often used as a coating on titanium alloys, steel, carbide, and aluminium components to improve the substrate's surface properties.

CENTRE AND SPOTTING DRILL BITS:Centre drill bits are used in metalworking to provide a starting hole for a larger-sized drill bit or to make a conical indentation in the end of a work piece in which to mount a lathe centre

A device used to inspect, measure, test, or examine parts in order to determine compliance with required specifications. A measuring instrument is a device for measuring a physical quantity. In the physical sciences, quality assurance, and engineering, measurement is the activity of obtaining and comparing physical quantities of real-world objects and events. Established standard objects and events are used as units, and the process of measurement gives a number relating the item under study and the referenced unit of measurement. Measuring instruments, and formal test methods which define the instrument's use, are the means by which these relations of numbers are obtained. All measuring instruments are subject to varying degrees of instrument error and measurement uncertainty.

Principles of bearing selection and application

The bearing arrangement of a rotating machine component, e.g. a shaft, generally requires two bearings to support and locate the component radially and axially relative to the stationary part of the machine, such as housing. Depending on the application, load, requisite running accuracy and cost, A bearing arrangement does not only consist of rolling bearings but includes the components associated with the bearings such as the shaft and housing. The lubricant is also a very important component of the bearing arrangement because it has to prevent wear and protect against corrosion so that the bearing can deploy its full performance. Beside these, the seal is also a very important component, the performance of which is of vital importance to the cleanliness of the lubricant. Cleanliness has a profound effect on bearing service life.

To design a rolling bearing arrangement it is necessary to select a suitable bearing type to, - Improve productivity
- Reduce maintenance costs
- Improve energy
- Efficiency
- Optimise designs,
- To determine a suitable bearing size, a suitable form and design of other components of the arrangement
- Appropriate fits and bearing internal clearance or preload
- Holding devices , Adequate seals ,The type and quantity of lubricant
- Installation and removal methods, etc.

Each individual decision affects the performance, reliability and economy of the bearing, which includes technical support about the selection of the right bearing as well as calculations, more limited the available experience of using bearings for particular applications, the more advisable it is to make use, noted that the values provided in the product tables for load and speedratings as well as for the fatigue load limit.
