Description of Diaphragm Valves

Diaphragm Valves consist of a Valves body with two or more ports, a diaphragm, and a “weir or saddle” or seat upon which the Diaphragm closes the valve. The basic construction of the Diaphragm Valves is quite simple. It is composed of three principal units called Body, Bonnet, and Diaphragm.

Diaphragm Valves are particularly designed for handling Corrosive, Abrasives, Viscous or Fibrous Fluids.

Advantages of Diaphragm Valves

• The most economical corrosion-free and resisting Valves available today.
• Adaptable Body and Diaphragm materials.
• Permanent air tightness against fiber and gases Resilient closure.
• No contamination. The most suitable for Nuclear & Food Services.
• No Gland packing.
• Simple in-line maintenance.
• Easy dismantling and assembly are possible without removing the body from the pipeline.

Maintenance of Diaphragm Valve

Maintenance of Diaphragm Valves is very simple. By dismantling the Bonnet from the Body, the whole Trim Assembly can be taken out for cleaning and maintenance while the Body will remain in the Pipeline. Hence the design allows maintenance to save time and energy. Its linear flow characteristics make it perfect for throttling or modulating operations. On/off and control, automation is supplied with Pneumatic Actuators or Cylinders.
