A diaphragm valve is used on shut-off and throttling service for liquids, slurries, gases and vacuum. Diaphragm valves seal by a flexible membrane (the diaphragm), being forced against a seat. The diaphragm seals by pressure exerted on it by a linear motion stem. The most common design is a weir diaphragm valve that has a transverse upstand in the valve body against which the diaphragm seals.
The linear mechanical operating parts of the diaphragm valve are isolated from the flow. This makes diaphragm valves suitable for viscous, abrasive and corrosive media also hazardous substances as its sealing system avoids any contamination towards or from the environment. They are well suited to the handling of multiple chemical applications of both clear, clean fluids as well as a wide range of slurries.
The plastic pneumatic diaphragm valve is commonly used in applications controlling neutral gases and fluids, pure and sterile media, hygienic, food and water, and aggressive or corrosive chemicals.
The most common automatic diaphragm valve is the pneumatic diaphragm valve or air actuated diaphragm valve as this construction creates a relatively inexpensive diaphragm control valve when compared to an electric diaphragm valve.
Allvalves can offer Gemu diaphragm valves, FIP diaphragm valves, Burkert diaphragm valves, CEPEX diaphragm valves and more.
