The flange swing check valve is a fundamental, robust, and widely used component for preventing backflow in piping systems. Its flanged ends make it ideal for bolted, permanent installations in medium to large pipe sizes where flow is consistent and the risk of water hammer is understood and managed.

Product Description
A Flange Swing Check Valve is a type of check valve (non-return valve) designed to allow fluid (liquid or gas) to flow through it in only one direction. The "swing" refers to the disc, which swings on a hinge or trunnion to open and close. The "flange" refers to the method of connection: it has flanged ends that bolt directly to matching flanges in a piping system.
Its primary purpose is to prevent backflow, which can damage equipment (like pumps and compressors), cause water hammer, or contaminate upstream media.
The flange swing check valve is a fundamental, robust, and widely used component for preventing backflow in piping systems. Its flanged ends make it ideal for bolted, permanent installations in medium to large pipe sizes where flow is consistent and the risk of water hammer is understood and managed.
Features
• Low Pressure Drop: The full-port design offers minimal resistance to flow when fully open.
• Simple Design: Few moving parts make them reliable and easy to maintain.
• Automatic Operation: Requires no external power or operator intervention.
• Suitable for Large Lines: Often used in large diameter piping systems.
