Frequently Ask Questions
A Pneumatic UPVC Socket Weld Diaphragm Valve is an automatically operated diaphragm valve with a UPVC body and socket-weld ends, designed for controlling and isolating compatible water, chemicals and corrosive fluids.
A socket-weld connection allows a compatible plastic pipe to be inserted into the valve socket and joined using the appropriate plastic joining method. It provides a compact and streamlined connection without the need for a flanged joint.
It depends on the process media.
EPDM is commonly suitable for water and many aqueous services.
PTFE offers broader chemical resistance and can be preferred for many aggressive chemical applications.
The final selection should be based on the exact chemical and temperature.
The exact joining method depends on the valve and piping material/design. For UPVC systems, socket connections are commonly joined using an appropriate solvent-cement process rather than metallic fusion welding. Always follow the valve and piping manufacturer's joining procedure.
Compressed air operates the pneumatic actuator, which moves the diaphragm to open or close the valve. The diaphragm separates the process fluid from the operating mechanism.
The diaphragm provides isolation between the process media and the valve operating components, which can help reduce contamination and corrosion of internal operating parts.
UPVC diaphragm valves are generally intended for low-to-medium pressure applications, depending on size, design and temperature. The manufacturer's pressure rating should always be confirmed.
