Industrial Grey PVC-U Pipe And Fittings PP-H Valves
PP-H Pressure Retaining / Relief Valve Type 586 ( also used as back pressure valve)
Operational Overview: Back Pressure (installed inline) Back pressure valves apply positive discharge pressure to a metering pump system to prevent siphoning and eliminate varying dosage rates caused by fluctuating downstream pressure. The diaphragm is held against the seat by an internal spring. When the preset pressure is exceeded, the diaphragm is forced up and chemical flows through the valve to the injection point. Operational Overview: Pressure Relief (installed on branch of main line) Operates when the pressure in the chemical system exceeds the preset pressure of the valve. The diaphragm is held against the valve seat by an internal spring. When the preset pressure is exceeded the diaphragm is forced up and the chemical flows out the relief port, back to the chemical tank or suction side of the pump.
