Applications:
Manually operated diaphragm valve is 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 valve is better in feature of flow in comparison with other valves. It si eaiser to clean up and better to process the sunstance with particles. The phenomenon of air pocket is rare during application of flow control.
Operating Principles:
The diaphragm provides the body seal as well as the seat seal. There are no paths to the outside environment so it's 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 flow path through body.
The inter relationship of body to the pressure plate prevents over compression of the diaphragm.
Valve Body:
Forging body blank is through a piece of stainless steel ingot, in the forging process, along with the high temperature forging provide, through extrusion blank shape change, through the forging after body dendity higher, the structure is more uniform, no sand hole and other impurities. Then through the processing center carry on the high precision machining.
Casting body is made by the mould paraffin wax model, paraffin wax model infiltratiion in ceramic, to let the whole body wax mold surface form a layer of strong ceramic. Melt wax modl, then into the melting of the stainless steel solution, after cooling knock off the appearance of ceramic, blank body is made up. Casting size is very accurate, the outward apperance is smmoth, clean and tidy.
