Stainless Steel Sanitary Diaphragm Valve And Check Valve
Stainless steel sanitary diaphragm valve
Manual or pneumatic operation, especially applied for the hygienic and aseptic processes in the pharmaceutical industry. The valve is ideal for fluid control and on / off tasks. Diaphragm provides body seal and valve seat seal. There is no path to the external environment, so the diaphragm is suitable for aseptic processes.
When the valve is closed, the pressure pad supported the diaphragm moves toward the sealing surface of the valve body. When the pressure plate moves, the diaphragm bends and is forced into the valve seat area in the center of the valve body, thereby closing the fluid path to the valve body. The sanitary diaphragm valves can be operated manually or pneumatically, and can be controlled by a controller and an electromagnetic valve.
Welded sanitary check valves are used in stainless steel piping systems to prevent fluid backflow.
Technical data of welding sanitary check valve:
If the check valve is installed in a vertical pipe, open the valve required pressure is about 300-600kpa, the maximum conveying pressure of 800kpa, temperature ranged according to the seal material selection.
Welded sanitary check valve material:304 stainless steel
Sealing ring: silicone rubber (VMQ), fluorine rubber (FPM) three ethylene propylene (EPDM)
Welding type sanitary check valve is installed in a vertical pipe, open the valve required pressure is about 300-600kpa, the maximum conveying pressure is 800kpa, temperature range according to the seal material selection.
