Diaphragm Valves

Diaphragm Valves

Diaphragm Valve is a quarter turn pipeline valve used to isolate or regulate the flow of fluid through a pipeline. A Diaphragm Valve consist of 5 main parts: body, seat, disc, stem and operator. These are light weight, cost effective, smaller face-to-face dimensions which needs less space for installation compared to other types of valves. Diaphragm Valves can be used in applications handling air, gases, steam, water, other liquid, slurries and vacuum service.

Ferrobend is a leading Diaphragm Valve manufacturer in India. We offer lug type, wafer type, flanged, double flanged, welded, double offset and triple offer Diaphragm Valves in cast iron, cast steel, stainless steel, bronze, duplex, super duplex alloy and many more. We can also produce high performance Diaphragm Valves for extreme temperature and high pressure service.

Diaphragm Valve Types

Diaphragm Valve Applications

Used across wide range of industrial sectors, Diaphragm Valve can be seen installed more often in pipelines handling large volume based liquids like water and slurries. Below are some common applications of Diaphragm Valves.

  • Cooling water, air and gases
  • Slurry and liquidised solids
  • High pressure and high temperature water service
  • High pressure steam service
  • Vacuum service
  • Compressed air and gases
