Manual diaphragm valves

Manual diaphragm valves are specially used for sanitary and aseptic processes in the pharmaceutical industry. The valve is ideal for fluid control and on/off tasks. Diaphragm provides body seal and seat seal. There is no path inside to the external environment, so the valve is suitable for sterile processes. When the valve is closed, the pressure pad supporting the diaphragm moves toward the sealing face on the valve body. As the pressure plate moves, the diaphragm bends and is forced toward the seat area in the center of the body, thereby closing the flow path to the body. The relationship between valve body and pressure plate prevents the diaphragm from squeezing.
