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
- *Efficiency and reliability through simplicity of design is the key to the superior performance and long life.
- *An optional closure device as lever arm and counterweight,spring,air cushioned cyliner,oil cushioned cyliner.
- *Efficient and positive sealing under most flow and pressure conditions. Valve close before flow reversal.
- *Unrestricted flow area combined with smooth streamlined contouring allows passage of large solids minimizing the potential for clogging,lower head loss,low pressure drop and reduced energy loss irrespective of pressure ratings
- *Full bore flow area, lower flow resistance.
- *Prevent medium back flow and eliminate destructive water hammer when the valve close. Protect the pipe system.
- *Fitted with cushion cylinder and lever weight, connected with disc by same shaft. The open and close time or speed can be adjusted by regulating valve and slide weight.
- *Sealing performance stable, reliable and wear resistance. Long use life, No vibration, No noise.
