Hayward Threaded Pressure Reducing Pressure Reducing Control Valve, 2 in Pipe Size – RPV1200TPE1
Help protect chemical feed systems from over pressure conditions with this HAYWARD pressure reducing control valve. When the preset pressure is exceeded (valve has an adjustment screw that you can adjust in the field), the diaphragm moves up and the chemical flows out of the relief port back to the chemical tank or the suction side of the pump.
