    Now, let us briefly know about the different types of Cast Check Valve available in the market. There are many types of it's that are common in the industry: swing check, disc check, split disc, diaphragm, and wafer check valve.

     

    These are a bit more complex valves that have a disc which is mounted on a spring for functionality. The pressure forces the inlets to open up, as it stretches the spring. When the water flow stops, the compression of the spring is great. This causes the disc to return to the initial position.

    Split disk check valves have a door split in the middle. This door regulates the flow of the liquid in one direction only. The fluid causes a pressure that enables the hinges to open.

     

    These are common valves, used in toilet tanks present in houses and so on. There are no balls controlling the flow. This valve uses small door on hinges whichis forced opened when the water or other fluidsare drawn. It closes when there is enough water, thus preventing the drainage of water from entrance of the shut off valve.
