ANSI Swing check valve-manufacture,factory,supplier from China

Check valve is to rely on the flow of the medium itself and automatically open and close valve disc, used to prevent the media flow back valve, also known as check valve, one-way valve, countercurrent valve, and back pressure valve.  Check valve is a kind of automatic valve, its main function is to prevent media backflow, prevent pump and drive motor reverse, as well as the discharge of container medium.  Check valves can also be used to supply lines in which pressure may rise to exceed system pressure in the auxiliary system.

Check valve refers to the hole and ultimate additives of the spherical disc and through its very own weight and media pressure generated movement to dam the media drift lower back valve.  automatic valve beauty, also known as take a look at valve, one-manner valve, backflow valve or isolation valve.  disc movement is split into lifting and swing.  lift check valves are similar in creation to globe valves besides for the stem that drives the disc.  the medium flows in from the inlet prevent (decrease facet) and flows out from the opening quit (better side).Cast Iron Wafer Ty

Check valve refers to the opening and closing parts of the circular disc and by its own weight and media pressure generated action to block the media flow back valve.  Automatic valve class, also known as check valve, one-way valve, backflow valve or isolation valve.  Disc motion is divided into lifting and swing.  Lift check valves are similar in construction to globe valves except for the stem that drives the disc.

At the contrary, the valve is closed while the medium flows back.  swing test valves have a disc this is tilted and rotates on its axis and paintings in a similar way to lift test valves.  check valves are often used as bottom valves in pumping units to save you the backflow of water.  check valves are combined with globe valves to provide safety isolation.  risks are large resistance, poor sealing when final.Cast Iron Wafer Type Check Valve Material:The body materia: GG25,GGG40,GGG50The disc material: DI/SS304/SS316/AL-BZThe stem/spring material: SS416/SS304The seat m
