Automatic Filter Control Valves

Working Principle
Using hermetic head faces theory, Runxin valve is designed to integrate multi-ports round closely to one
valve body. When the rotor rotates, some ports will be shut off and meanwhile some other ports wil be
open, and thus the water willflow in and out this valve.
