Pneumatic Diaphragm Valve
●Diaphragm valves, manually or pneumatically operated, are specifically designed for hygienic and aseptic processes in the pharmaceutical industries.
●The valve is excellent for flow control as well as for open/close duties.
●The diaphragm provides body seal as well as seat seal. There are no paths to outside environment so it is suitable for aseptic processes.
● When valve is closed, a pressure pad which supports diaphragm to move towards sealing face on body. When pressure plate moves, diaphragm flexes and is forced down onto seat area in the centre of body, thus it closed off flow path through body.
● The interrelationship of body is to prevent the compression of diaphragm.
● The valve can be manually/pneumatically operated, and can be controlled by control tops and solenoid valves.

Manual or pneumatic operation, specifically for sanitary and aseptic processes in the pharmaceutical industry. This valve is ideal for fluid control and on/off tasks. The diaphragm provides a body seal and a seat seal. There is no path to the outside environment, so the diaphragm valve is suitable for aseptic processes. When the valve is closed, the pressure pad supporting the diaphragm moves toward the sealing surface on the valve body. As the
pressure plate moves, the diaphragm bends and is forced to the seat area in the center of the valve body, thus closing the fluid path to the valve body. The relationship between the valve body and the pressure plate prevents the compression of the diaphragm. The valve can be operated manually or pneumatically, or it can be controlled by a controller and solenoid valve.
