Description
Flanged Lift Check Valve is a lift check valve with a guided disc that moves up and down. Flow lifts the disc; when flow stops, the spring and the disc weight seat it for tight shut-off.

Selection and Installation
Size a check valve by the flow rate, not only by the pipe size; in an oversized valve the disc cannot open fully and flutters. Install it with the arrow on the body pointing in the flow direction. A strainer upstream extends its service life.
