APPLICATION
Diaphragm valve,manually or pneumatically operated,and specifically designed for for using on hygiene and
aseptic processes in the pharmaceutical industries. The valve is excellent for flow control as well as for open
and close duties. The diaphramg valve are better in feature of flow in comparison with other valves, it is easier
to clean up and better to process the substance  with particles,the phenomenon of air pocket  is rare duringÂ
application of flow control.Â
OPERATING PRINCIPLES
The diaphragm provides the body seal as well as the seat seal.There are no paths to the outside environment
so it suitable for aseptic processes. When the valve is closed a pressure pad which supports the diaphragm
moves towards the sealing face on the body.When 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
inter relationship of body to the pressure plate prevents over compression of the diaphram.The valve can be manual operation and pneumatic operation control tops of solenoid valves.
KEY FEATURES
1,Facing the customer's special needs of the design. 2,The structure is compact,small installation space.
3,Different size can be combination. 4, Optimization of the self emptying function. 5, Zero dead angle.
6, Reduce the contact area,prevent medium retention,and cross infection. 7, Save joint,pipe welding. 8,
Reduce the need for valve various qualification certification. 9, According to customer's requirment to choose
actuator and connections.
