All Thermoplastic diaphragm Pressure Relief Valve for protecting against over-pressure in Chemical Feed Systems. When the preset pressure is exceeded, the diaphragm is forced up and the chemical flows out of the relief port, back to the chemical tank or the suction side of the pump. All valves are preset at 50 psi, however they are field adjustable via the adjustment screw. Relief valves should be set approximately 15 psi higher than the system pressure. Installation should always be made as close to the pump as possible, without any valves or accessories between the relief valve and the pump. Valves have PVC bodies with a PTFE/EPDM diaphragm and 304 SS bolting. Valves have an adjustment screw with slot. Spring is rate for 10 to 150 psi and is preset to 50psi. Valves are rated to 250 psi at 70¡«F/17.2 Bar at 21¡«C. Common applications include chemical dosing, transfer and processing and chlorination systems.
