Ball check valves are commonly used in water and wastewater applications. They have very simple operation, and are compact and economical too. Ball check valves feature a rubber coated ball that moves in and out of the seat as flow moves forward and reverse.
Tilting Disc Check Valve offers significant energy savings compared to other types of conventional check valves because of its larger flow area and low head loss characteristics. Tilting Disc Check Valve achieves full opening when the disc “tilts” in the flow of the media. Tilting Disc Check Valve is a cost-effective valve with a unique design that provides excellent tightness and minimizes water-hammering.
DIN dual plate check valve is one type of non-return valve with two torsion springs added to each of pair valve plates,which close the plates quickly and automatically, preventing the mediums from flowing back. Wafer dual plate check valve can be mounted between the two pipes in both horizontal and vertical directions. Wafer type dual plate check valve has features of compact structure, light weight and bidirectional
ANSI dual plate check valve role is only to allow the medium to flow in one direction, and prevent the direction of flow. Usually it is automatic, in one direction flow of fluid pressure, disc open; when the fluid flows in the opposite direction, the self-coincidence disc of the fluid pressure and the disc acts on the seat, thus cutting off the flow.
Stainless steel dual plate check valve are used in piping systems to prevent backflow of media. Prevent the pump and its driving motor from reversing, as well as the discharge of the medium in the container. Stainless steel check valves can also be used to supply lines in which pressure may rise to exceed that of the auxiliary system. Stainless steel check valve according to the different material, can be applied to all kinds of media pipeline.
Iron dual plate check valve ‘s structure similar to butterfly valve, its simple structure, small flow resistance, water hammer pressure is also small. Can be installed in both horizontal and vertical ways. The lightweight and compact design greatly reduces installation costs. Its compact design minimizes the distance between flanges, making it easy to fit between all flanges .
