PVC Back Pressure Valve model RPV165 is a spring type plastic Back Pressure Valve. it is produced and designed as per standard DIN, ANSI, JIS, BS. PVC Back Pressure Valve made by PVC body, with PTFE/EPDM diaphragm and sealing, pressure regulating range 0 to 1.0Mpa. size from 15mm (1/2") to 65mm(2-1/2"), socket and flange end for optional. PVC Back Pressure Valve has good property of Corrosion resistance and suitable for water treatment and chemical mediums.

Back Pressure Valve is a special valve whose opening and closing parts are normally closed under the action of external force. When the medium pressure in the equipment or pipeline rises beyond the prescribed value, the medium is discharged to the system to prevent the medium pressure in the pipeline or equipment from exceeding the prescribed value. Back Pressure Valve is an automatic valve, mainly used in boilers, pressure vessels and pipes, control pressure does not exceed the prescribed value, play an important role in protecting personal safety and equipment operation.
