DIAPHRAGM VALVE MANUFACTURERS IN INDIA

Speciality Valve is a leading Diaphragm Valve Manufacturers in India, offering precision-engineered valves best applicable in processes requiring leak-tight sealing and contamination-free flow. Speciality Valve’ diaphragm valves are designed to be tough, chemical-resistant, and maintenance-free for operation in critical industrial processes.

Why Is It Needed?

Diaphragm valves are applied wherever tight shut-off, reliability, and sanitation are mandatory. They are used in corrosive fluid service, slurries, or high-purity operations in which other valves will be ruined or allow contamination. They are applied on sensitive systems because their body which is sealed and non-turbulent flow stream.

Major Components of Diaphragm Valve:

1) Valve Body: The valve body encloses the diaphragm and governs flow path
2) Diaphragm: Elastic membrane which serves as the flow control element
3) Compressor: Squeezes the diaphragm to close or open the valve
4) Bonnet: Protects the stem and actuator
5) Actuator/Handwheel: Manually or automatically operates valve movement

Working of Diaphragm Valve:

Diaphragm valves function by the motion of a flexible diaphragm moving up and down to control the flow of the fluid. When operated by an actuator or handwheel, the diaphragm seals against a seat or weir within the valve body to close or allow the flow. The configuration provides excellent sealing and internal leakage protection.
