Manual and mechanical valves05

Swing check valve

A swing check valve opens its disc with forward flow and closes automatically on reversal to prevent backflow. Fluid velocity, reverse pressure, installation direction, disc mass and water-hammer risk are central selection factors.

Application and duty

Protecting pumps, compressors and lines where reverse flow is harmful

TECHNICAL REFERENCE
