Piston Valves

Psiton Valve is basically a seatless,glasses,soft seated globe value particularly for zero leak operations upto class 300.They are avaliable upto 500 NB size in forged steel(A105-) and upto 200 NB and in cast steel(ASTMA 216, GR. WCB).

Gate, Globe & Check Valves upto Class 2500 LBS

We supply gate valves, also referred to as the sluice valve that opens up by lifting a gate/wedge and is at times used to restrict the flow of fluids as either it opens up or shuts up completely. When open it does not restrict the passage of flow and as a result it leads to low friction loss. Characteristically the rising stem used for visual indication of valve position, non rising stem used where in the vertical space is restricted and the bonnets, be it union,bolted or pressure seal, each one is designed to efficiently function as leak proof closure for the valve body. We supply gate valves of standard dimensions and also make sure that our manufacturers make use of high quality cast iron, cast carbon steel, gun metal, stainless steel, alloy steels and forged steel.

Steam Traps, Stainers, DCV SteamSeparators, Condensate recovery pump

A steam trap is a device used to discharge condensate and non condensable gases while not permitting the escape of live steam. Nearly all steam traps are nothing more than automatic valves. They open, close or modulate automatically.
The three important functions of steam traps are:
1) To discharge condensate as soon as it is formed.
2) Not to allow steam to escape.
3) To be capable of discharging air and other incondensible gases

Control Valves Saety Relief valves Pressure Reducing Valves

The control valve is the most important single element in any fluid handling system, because it regulates the flow of fluid to the process. To properly select a control valve, a general knowledge of the process and components is usually necessary. This reference section can help you select and size the control valve that most closely matches the process requirements.
The sizing of a valve is very important if it is to render good service. If it is undersized, it will not have sufficient capacity. If it is oversized, the controlled variable may cycle, and the seat, and disc will be subject to wire drawing because of the restricted opening

Diaphragm Valves,m Knife Edge gate valves, Water check valves.

Diaphragm valve is recommended for application involving slurries, fluids with suspended solids, corrosive fluids etc. This valves provide tight shut off and are primarily designed for on-off services. Diaphragm valves give best services to water, chemical

Butterfly valves, Balancing valves & Dual plate, Check Valves upto 1100mm

A butterfly valve is a type of flow control device, typically used to regulate a fluid flowing through a section of pipe. The valve is similar in operation to a ball valve. A plate or disc is positioned in the center of the pipe. The disc has a rod through it connected to an actuator on the outside of the valve. Rotating the actuator turns the disc either parallel or perpendicular to the flow. Unlike a ball valve, the disc is always present within the flow, therefore a pressure drop is always induced in the flow, regardless of valve position

Industrial Gaskets, Spiral Wound, Pure/Expanded Graphite

The spiral wound gasket depends upon the mechanical characteristics of a formed metal spiral strip, rather than the compressive virtues of more traditional gasket materials. This makes it particularly suitable for low or fluctuating bolt loads. The sealing strips, or fillers, are usually graphite, although other materials such as Teflon® may be used, the windings are always s/steal. For this type of gasket to work the spiral must not be over compressed, hence one of two types of compression control is usually used.

Orifice Plate,Flange Nozzle

Orifice Plates The orifice plate is the simplest of the flow path restrictions used in flow detection, as well as the most economical. Orifice plates are flat plates 1/16 to 1/4 inch thick. They are normally mounted between a pair of flanges and are installed in a straight run of smooth pipe to avoid disturbance of flow patterns from fittings and valves. Three kinds of orifice plates are used: concentric, eccentric, and segmental. The concentric orifice plate is the most common of the three types. The orifice is equidistant (concentric) to the inside diameter of the pipe. Flow through a sharp-edged orifice plate is characterized by a change in velocity. As the fluid passes through the orifice, the fluid converges, and the velocity of the fluid increases to a maximum value. At this point, the pressure is at a minimum value. As the fluid diverges to fill the entire pipe area, the velocity decreases back to the original value. The pressure increases to about 60% to 80% of the original input value. The pressure loss is irrecoverable; therefore, the output pressure will always be less than the input pressure. The pressures on both sides of the orifice are measured, resulting in a differential pressure which is proportional to the flow rate. Segmental and eccentric orifice plates are functionally identical to the concentric orifice. The circular section of the segmental orifice is concentric with the pipe. The segmental portion of the orifice eliminates damming of foreign materials on the upstream side of the orifice when mounted in a horizontal pipe. Depending on the type of fluid, the segmental section is placed on either the top or bottom of the horizontal pipe to increase the accuracy of the measurement. Eccentric orifice plates shift the edge of the orifice to the inside of the pipe wall. This design also prevents upstream damming and is used in the same way as the segmental orifice plate. Orifice plates have two distinct disadvantages; they cause a high permanent pressure drop (outlet pressure will be 60% to 80% of inlet pressure), and they are subject to erosion, which will eventually cause inaccuracies in the measured differential pressure.
An orifice plate is a device used to measure the rate of fluid flow. It uses the same principle as a Venturi nozzle, namely Bernoulli's principle which says that there is a relationship between the pressure of the fluid and the velocity of the fluid. When the velocity increases, the pressure decreases and vice versa. An orifice plate helps measures flow through the differences in pressure from the upstream side to the downstream side of a partially obstructed pipe. The plate offers a precisely measured obstruction that narrows the pipe and forces the flowing substance to constrict. A DP cell allows the comparison of the pressure on the upstream (unobstructed) side and the downstream (constricted) side.


A flange is an external or internal rib, or rim (lip), for strength, as the flange of an iron beam or I-beam (or a T-beam); or for a guide, as the flange of a train wheel; or for attachment to another object, as the flange on the end of a pipe, steam cylinder, etc, or on the lens mount of a camera. Thus a flanged rail is a rail with a flange on one side to keep wheels, etc., from running off. The term "flange" is also used for a kind of tool used to form flanges. By the use of Flanges we can assemble or dissamble the pipes very easily.

Expansion Bellow

Our range of axial expansion bellows is used for higher pressures. Axial expansion bellows are installed in pipe work and duct systems to prevent damage caused by thermal growth, vibration, pressure thrust and other mechanical forces. There is a wide range of axial metallic bellows designs in a variety of materials. Options range from the simplest convoluted bellows used in petroleum refineries. These are made up of various materials including all types of stainless steels and high-grade nickel alloy steels.

Metering components were selected to withstand demanding industrial use including continuous operation, repeated chemical washdown, and outdoor applications.

Principle of Operation
venturi flow nozzle characterized by a convergent bellmouth inlet, minimum area throat, and conical diffuser. Upstream pressure is converted to velocity as steam flows through the converging inlet. The velocity increases along the restrictive inlet until sonic velocity is achieved at the nozzle throat. The sonic velocity or speed of sound, is the maximum obtainable speed at which the flow may pass through the nozzle throat. The sonic velocity is converted back to static pressure in the diffuser.
Mass flow rate is strictly proportional to the upstream pressure. Changes in the downstream pressure do not affect upstream conditions. A downstream change in pressure can not be transmitted through the sonic flow conditions existing at the throat For the system to operate correctly, a small pressure drop across the nozzle is required. The proprietary inlet, throat, and diffuser design is such that the exit pressure may be as high as 90% of the inlet pressure for acceptable operation. Steam to atmosphere and open tank applications easily meet these operating conditions.

Ball Valves

A ball valve is a valve that opens by turning a handle attached to a ball inside the valve. The ball has a hole, or port, through the middle so that when the port is in line with both ends of the valve, flow will occur. When the valve is closed, the hole is perpendicular to the ends of the valve, and flow is blocked. The handle or lever will be inline with the port position letting you "see" the valve's position. The ball valve, along with the butterfly valve and plug valve, are part of the family of quarter turn valves.
Ball valves are durable and usually work to achieve perfect shutoff even after years of disuse. They are therefore an excellent choice for shutoff applications (and are often preferred to globe valves and gate valves for this purpose). They do not offer the fine control that may be necessary in throttling applications but are sometimes used for this purpose.
Ball valves are used extensively in industry because they are very versatile, pressures up to 10,000 psi, temperatures up to 200 Deg C. Sizes from 1/4" to 12" are readily available They are easy to repair, operate manually or by actuators. The body of ball valves may be made of metal, plastic or metal with a ceramic center. The ball is often chrome plated to make it more durable.

Two way, or Three way ball valves

schematic 3 way ball valve - L-shaped ball right, T-shaped left Three-way ball valves have an L- or T-shaped hole through the middle. The different combinations of flow are shown in the picture.Multi-port ball valves with 4 ways, or more, are also commercially available, the inlet way often being orthogonal to the plane of the outlets. For special applications, such as driving air-powered motors from forward to reverse, the operation is performed by rotating a single lever 4-way ball valve. The 4-way valve has two L-shaped ports in the ball that do not interconnect, sometimes referred to as an "×" port.
Ball valves in sizes up to 2 inch generally come in single piece, two or three piece designs. One piece ball valves are almost always reduced bore, are relatively inexpensive and generally are throw-away. Two piece ball valves are generally slightly reduced (or standard) bore, they can be either throw-away or repairable. The 3 piece design allows for the center part of the valve containing the ball, stem & seats to be easily removed from the pipeline. This facilitates efficient cleaning of deposited sediments, replacement of seats and gland packings, polishing out of small scratches on the ball, all this without removing the pipes from the valve body. The design concept of a three piece valve is for it to be repairable.
