Cast iron diaphragm valve manufacturers in India

Speciality Valve is one of the largest Cast iron diaphragm valve manufacturers in India offering heavy-duty, corrosion-resistant diaphragm valves for various applications in the industries. Our diaphragm valves are designed to deliver accurate control and shut-off, particularly for corrosive and viscous fluid-handling systems.

What is it?

Diaphragm valves are used to control the flow of different fluids with the help of a flexible diaphragm that seals against a seat in an attempt to control or shut off the flow. Because they are cast in cast iron, the valves become very resistant and cost-effective for non-aggressive media and low to moderate pressure processes.

Why Required?

In most applications, contamination, leakage, or corrosive/particulate-contaminated media-induced wear must be avoided. Cast iron diaphragm valves provide a leak-tight, low-maintenance, and hygienic solution and are hence ideal for the task.

Key Components of Cast Iron Diaphragm Valve:

Body: It is constructed of high-grade cast iron for ruggedness and economy.

Diaphragm: It is usually constructed of rubber, PTFE, or other elastomers based on the media.

Bonnet: Encloses the actuator and retains the diaphragm mechanism.

Compressor: Pushes against the diaphragm to close the valve.

Working of Cast Iron Diaphragm Valve:

The diaphragm is compressed by a compressor to seal against the valve body seat, stopping the flow. When the actuator is activated in the reverse direction, the diaphragm opens to permit flow. The minimum contact of this design provides minimal between the moving parts and process fluid.
