A device used to increase the pressure in a pipeline. When the pressure of the dosing point is lower than the inlet pressure of the metering pump, the back pressure valve must be installed at the outlet of the metering pump to reduce the overcurrent conveying caused by siphoning and self-flow, and to ensure that the metering accuracy of the metering pump is not affected.
Maximum flow: 18000L/h
Maximum pressure: 1.3Mpa
