Industrial Valves Manufacturer in India

While they all serve similar functions, industrial valves have evolved into different types with specialized designs and features to meet a wide range of application requirements. The most common types of valves and their ideal applications are discussed below.

• Balancing Valv

Balancing valves are used to control flow throughout a system by regulating flow between multiple flow branches. These valves serve a variety of critical functions in HVAC systems and fluid power applications. Balancing valves, for example, allow GPM to be adjusted in commercial heating and cooling systems under changing loading conditions. They can also be used to balance the load of double-acting cylinders by applying a counterbalancing force.

• Ball Valve

A ball valve is a quarter-turn valve with a hollow, ball-shaped insert for controlling fluid flow. The valve can be quickly opened or closed by turning the valve handle 90 degrees. Ball valves, with their relatively simple designs, are low-maintenance, long-lasting, and leak-free when used properly.

These valves are commonly used in fluid, gas, and vapor applications that require bubble-tight shut-offs. Although ball valves with metal seats are most commonly used in low-pressure applications, they can also be used in high-pressure, high-temperature environments.

Industrial ball valves are classified into the following types:

• A gas ball valve is a type of ball valve that must be certified by the Canadian Standards Association (CSA) before it can be used safely in combustible gas applications. CSA-certified valves have undergone rigorous quality testing in accordance with US laws and other independent organizations (UL, ANSI, NSF, etc.).

• EzPress/EzGrip Ball Valve: These ball valves are ergonomically designed for easy and quick activation or deactivation in industrial applications. These valve connections are intended to save both time and money during installation.
• PEX valves are two-way, full-port, quarter-turn valves that are commonly used to shut down the water supply to plumbing fixtures and other appliances during repair or maintenance. The most popular pex connections are F-1960, F-1807, and Everloc +.

PP-R valves are designed to work with PP-R pipes, which are straight and rigid cylindrical pipes used to transport fluids in industrial applications. PP-R pipes and valves are highly resistant to corrosive chemicals and abrasives due to their polypropylene composition. This system creates socket and butt-weld connections using both heat welding and electrofusion.

• Butterfly Valve

A butterfly valve is a quarter-turn valve with a rotating metal disc that, when closed, is perpendicular to fluid flow. The intermediate rotations of the disc allow for precise control over the amount of liquid flowing through a system. They are available in both wafer and lug styles. Their high accuracy and reliability make them well-suited for a variety of industrial applications, including:

1. Water supply
2. Wastewater treatment
3. Fluid-handling power applications.
4. Pharmaceutical, chemical, and food processing services

• Gate Valve

Gate valves are primarily intended to block flow rather than regulate it. They contain a plate-like barrier (gate) that can be inserted into a fluid stream to prevent flow. Gate valves have some operational similarities with globe valves, but they provide less flow restriction when fully opened.

When compared to globe valves, gate valves have significantly lower head loss due to their unobstructed flow paths. Gate valves, on the other hand, are not intended for throttling and may not provide the positive shut-off that globe valves do. Gate valves are commonly used in wastewater, power, and process plants to provide shut-off or isolation capabilities.

• Globe Valve

A globe valve is a type of linear motion valve that stops, starts, or regulates flow in pipelines using a disc with a globe shape. To limit flow, close the movable disc, also known as a plug, against a stationary ring seat. Manually operated globe valves use handwheels to control disc movement, whereas automatic globe valves use actuators and sliding shafts.

Globe valves are more leak-resistant than other valves and have a shorter opening-closing time. These general-purpose valves are primarily used to turn off and regulate high-temperature applications such as wastewater treatment plants, process plants, and food processing plants.

• Check Valve

Check valves are automatic one-way valves that only allow fluid to flow in one direction. Pumps, gas lines, HVAC systems, and other applications that require one-way fluid movement rely on these valves. Check valves come in several varieties, including:

• Lift-type check valves allow fluid to flow by opening a ball or piston under a specified pressure. A decrease in pressure will push the piston or ball into the valve seat, closing the valve and preventing backflow.
• Swing check valves use a hinged disc that swings away from the valve seat to allow flow in the forward direction. If the upstream flow is interrupted, the disc returns to the valve seat, preventing backflow.
• A butterfly check valve is made of two half-circle gates that are hinged together. Forward flow pushes the gates open, while reverse flow causes them to retract.
