The seal materials comply with FDA177.2600 standard. Using
proprietary technology, the diaphragm uses a combination of EPDM
and PTFE, which is secured using SS bolts. The sealing part where
contact with the medium is of PTFE material, it has good cold
resistance -13°F (-25°C), excellent heat-resistance 482°F (+250°C),
tolerance to most chemicals, and excellent abrasion resistance to
medium flow.
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.
