What is a Diaphragm Seat Valve?

In the case of diaphragm seat valves, the tight shut-off of the volume flow takes place via a diaphragm.

What are the benefits of Diaphragm Seat Valves?

• Small dimensions -> low construction volume

• Damped operation

• High flow rate

• Inexpensive valve

Where are they used?

Diaphragm seat valves are best used in water-supply systems, everywhere where differential pressure is available.

How do they work?

The principle of the diaphragm seat valve is similar to that of the piston seat valve. But in this case the sealing element is clamped between body and cover and the stroke movement is determined by the special form and elasticity of the diaphragms.
