Diaphragm valve manufacturer in India

 Specialityvalve is the foremost Diaphragm Valve Manufacturer in India. Diaphragm valves are also known as membrane valves. It consists of a valve body with two or more ports as an elastomeric diaphragm and a weir and saddle or seat upon which the diaphragm closes the valve. It is constructed from plastic, metal, wood, or other material depending on the intended use.

Diaphragm valves can be manual or automated. Automated diaphragm valves may use pneumatic, hydraulic, or electric actuators along with accessories such as solenoid valves which limit switches and positioners.

Diaphragm valves are ideally suited for corrosive applications where the body and materials can be chosen for chemical compatibility, abrasive applications where the body lining is designed to withstand and easily replaced once it has worn out, and solid entrained liquids since it can seal around any entrained solids and provide a positive seal. 

Many diaphragm valve body dimensions follow the Manufacturer Standardization Society but most of them make it difficult to use diaphragm valves as an alternative. It is interchangeable with the most solid wedge, double disc, and resilient wedge gate valves as well as pattern plug and ball valves.
