Diaphragm valves, manually or pneumatically operated, and specifically designed for use on hygiene and aseptic processes in the pharmaceutical industries.
The valve is excellent for flow control as well as for open/ close duties.
The diaphragm valves 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 during application of flow control.
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 diaphragm.
The valve can be manual operation and pneumatic operation control tops of solenoid valves.
