VeeValv Diaphragm Valve
Diaphragm valves, manually or pneumatically operated, are specially designed for use in hygienic and aseptic processes in the food-processing and pharmaceutical industries.
The valve is excellent for flow control as well as for open/close duties.
The diaphragm provides the body seal as well as the seat seal. 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 inter-relationship of body to the pressure plate prevents over compression of the diaphragm.
The diaphragm valve can be actuated either manually or pneumatically (stainless steel pneumatic diaphragm valve) and controlled by control tops and solenoid valves.
