Description
Flanged Swing Check Valve is a flanged swing check valve. Flow swings the disc open on its hinge; when flow stops, the disc returns to its seat by its own weight and the back pressure. It offers low pressure loss when fully open.

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.
