Product Introduction:

18640 safety valve/back pressure valve UPVC/18632 safety valve 18640 back pressure valve 18650 plastic UPVC safety valve back pressure valve/18615 safety valve 18620 back pressure valve 18625 UPVC back pressure valve safety valve/UPVC back pressure valve/UPVC safety valve/UPVC articulated back pressure valve/UPVC flange back pressure valve/plastic back pressure valve 18615, 18620, 18625, 18632, 18640, 18650, 18665 plastic safety back pressure valveInstalled on the positive pressure discharge pipeline of the metering pump to prevent siphon phenomenon and eliminate changes in dosage caused by pressure fluctuations at the injection point. Remove the protective cap on the adjustment screw on site, rotate the adjustment screw, and use the pressure gauge in the pipeline to adjust the required pressure. The back pressure can be set within the range of 0-0.6Mpa by adjusting the screw. Used in conjunction with pulse dampers to reduce water hammer damage to the system, maintain a constant pressure from the pump outlet to the back pressure valve, and keep the system flow rate constant.

Backpressure valve safety valve diameter: DN15, DN20, DN25, DN32, DN40, DN50, DN65

Set back pressure range: 0.03-0.6Mpa

safety valveIntroduction:

The diaphragm and valve core are pressed against the valve seat by internal springs. 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 is not allowed to exceed the maximum pressure of the metering pump. It is generally installed 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.
