Back Pressure valve / counterbalance valve  背压阀

When medicine dosing point is lower than the outlet of metering pump, back pressure valve shall be installed at the outlet of metering pump in order to reduce siphon and excess feeding, and ensure the metering accuracy of metering pump is not affected.

在管路或是设备容器压力不稳的状态下，能保持管线所需压力，使泵能正常输出流量。另在泵的出端由于重力或其它作用常会出现虹吸现象，此时背压阀能消减由于虹吸产生的流量及压力的波动。

常用材料:PVC, SUS304, SUS316, PTFE
