Diaphragm Valve DN15 to DN300

The basic construction of the Diaphragm Valve is quite simple. It is composed of three principal units called Body, Bonnet and Diaphragm. Originally, the diaphragm valve was developed for use in industrial applications. Later on, the design was adapted for use in the bio-pharmaceutical industry by using compliant materials that can withstand sanitizing and sterilizing methods.

Diaphragm valves are particularly suitable for service lines handling Corrosive, Abrasives, Viscous or Fibrous Fluids.

There are numerous combinations available for selecting the most suitable body material, body lining and diaphragm material for a specific service depends on several variables, economic considerations nature of fluid handled, its concentration and corrosiveness, temperature, pressure, velocity and continuity of flow.

Diaphragm life depends not only upon the nature of the fluid handled but also upon the temperature, pressure and frequency of operations.

There are two main categories of diaphragm valves: one type seals over a “weir” & and the other (sometimes called a “full bore or straight-way” valve) seals over a seat.

These Valves can be effectively used to handle Pharmaceuticals, Foods, Dairy Products, as well as Beverages & Water Treatment Plants.
