The safety back pressure valve UPVC/CPVC/PVDF can prevent the occurrence of siphon phenomenon

Safety back pressure valve UPVC/CPVC/PVDF, UPVC back pressure valve/CPVC back pressure valve/PVDF back pressure valve/304 stainless steel back pressure valve, UPVC safety back pressure valve/CPVC safety back pressure valve/PVDF safety back pressure valve/304 stainless steel safety back pressure valveIt is mainly pressed against the valve seat by the diaphragm, valve core, and internal spring. When the pressure in the system pipeline exceeds the preset pressure, the diaphragm and valve core are lifted, and the medium leaks out to the return pipe and container. On site, the pressure can be set within the range of 0-1.0Mpa by adjusting the screw with the help of the pressure gauge in the pipeline. The relief pressure is generally set 0.1-0.2Mpa higher than the system pressure. The pressure regulation of the safety valve should not exceed the maximum pressure of the metering pump. The installation should be as close as possible to the outlet of the pump, and there should be no valve between the pump and the safety valve. Protect the safety of the pump and ensure the normal operation of the system.
