INTRODUCTION
Donjoy specializes in manufacturing and exporting valve,pump,fitting for over 20 years with good quality and pretty competitive price. Products are with 3A,CE,FDA cetification and production management is according to ISO9001-2008.
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 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 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
