GM-NO.4004 Sanitary Welded Pneumatic Diaphragm Valve
Application:
GM-NO.4003 Series is a Actuator type sanitary pneumatic diaphragm valve with weld ends, which is widely used in stainless steel pipe system to prevent reverse flow.
Operating Principle.
The diaphragm Provides the body seal as well as the seat seal.
There are no paths to the outside environment and as such the valve is suitable for aseptic processes. As the valve is 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 valve can be actuated either manually or pneumatically and controlled by control tops and solenoid valves.
Technical Specifications:
Max.pressure: 10Bar (145PSI)
Working temperature: -10℃ to +120℃(EPDM) -14°F to 248°F(+140℃(SIP,max. 30min)284°F)
Approved according to directive PED 97/23/EC
Design and Features:
They 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.
