Hygienic Pneumatic Diaphragm Valve Controlled By Control Units And Solenoid Valves
Descriptions:
The diaphragm provides the body seal as well as the seat seal. There are no paths to the outside environment and, as such, the valve is suitable for aseptic processes. When the valve is being closed, a pressure pad which supports the diaphragm moves towards the sealing face on the body. As the pressure plate moves, the diaphragm flexes and is forced down onto the seat area in the centre of the body, thus, closing off the flow path through the body.
The valve can be actuated either manually or pneumatically and
controlled by control units and solenoid valves.
A standard diaphragm valve is used to shut the flow of a line, an
NDL type valve shuts only one outlet of the main line.
Applications:
Diaphragm valves, ,manually or pneumatically operated, are
specially designed to use on hygienic and aseptic processes in the
pharmaceutical industries, The valves is excellent for flow control
as well as for on/off duties. Diaphragm valves are widely applied
to CIP/SIP.
Operating principles:
The diaphragm provides the body seal as well as the seat seal.
There are no paths to the outside environment and as such the valve
is suitable for aseptic processes.
As the valve is closed a pressure pad which supports the diaphragm
moves towards the sealing face on the body. As the pressure plate
moves the diaphragm flexes and is forces down onto the seal area in
the centre of the body thus closing off the flow path through the
body.
The inter-relationship of body to the pressure plate prevents over
compression of the diaphragm. The valve can be actuated either
manually or pneumatically are controlled by control tops and
solenoid valves.
