Description
Stainless Steel Disco Check Valve is a spring-loaded disc check valve installed between two flanges. Flow lifts the disc against the spring; when flow stops, the spring presses the disc back onto its seat and blocks backflow. Thanks to the spring it can be installed in any position, horizontal or vertical.

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.
