Product description

The check valve is a type of shut-off valve. In the intended flow direction (A to B) the medium can pass freely through the valve, but in the reverse direction flow is prevented.
The check valve RV 25 basically consists of a housing with an integrated valve seat, a closing cone and a spring. The spring presses the closing cone onto the valve seat. Flow in the direction from B to A is prevented.
In this application, it is used to maintain a certain pressure in seal gas systems.
