Cast Iron Swing Check Valve

Description

The Cast Iron Swing Check Valve is a flanged non return valve that allows flow in one direction only. The disc swings open with forward flow and closes automatically under gravity and reverse flow, protecting pumps and equipment from backflow. Its full-bore flow path gives low pressure loss, and the cover can be removed for inspection without taking the valve out of the line.
