DIN F1 LIFT CHECK VALVE

DIN F1 LIFT CHECK VALVE

A lift check valve is a check valve in which the disc, sometimes called a lift, can be lifted up off its seat by higher pressure of inlet or upstream fluid to allow flow to the outlet or downstream side. A guide keeps motion of the disc on a vertical line, so the valve can later reseat properly. When the pressure is no longer higher, gravity or higher downstream pressure will cause the disc to lower onto its seat, shutting the valve to stop reverse flow.

F1 lift check valve is one type of lift check valve. The specifications are as below:
