Back Flushing Valve
A fully automatic backwash filtration system dedicated hydraulic control valve, driven by the pressure of the pipeline system, can automatically carry out two-way switching, to achieve an automatic backwash filter. The diaphragm drive structure requires only a short stroke to smoothly change the flow of water, close the inlet when the backwash port is open, and vice versa. Avoid filter overflows or water mixing with wastewater.
