What’s cast iron swing check valve?
Cast Iron Swing Check Valve consists of a valve body,a bonnet,and a disc that is connected to a hinge. The disc swings away from the valve-seat to allow flow in the forward direction,and returns to valve-seat when upstream flow is stopped,to prevent back flow.it allows full,unobstructed flow and automatically closes as pressure decreases.These valves are fully closed when the flow reaches zero and prevent back flow.Turbulence and pressure drop within the valve are very low.The valve is opened by the fluid flow in one direction and closes automatically to prevent flow in the reverse direction.
the valve is made of cast iron,ductile iron, is mainly used for water supply and drainage system, and other industrial sectors of the pipeline outlet to prevent medium countercurrent in low pressure and normal temperature.
Main features of cast iron swing check valve
Features and benefits of Cast Iron Swing Check Valve
- *Trouble-free operation and easy maitanance
