5603 Henry Pressure Relief Valves, Ductile Iron, Angle Type, 1" FPT X 1-1/4" FPT

Henry 5603 Pressure Relief Valves, Ductile Iron, Angle Type, 1" FPT X 1-1/4" FPT

The main function of a Pressure Relief Valve is to protect against accidental over-pressure of a pressure vessel due to system malfunction or fire.

Applications

Henry Technologies' Relief Valves are designed to be used in refrigeration systems to prevent over-pressure due to system malfunction or excessive external heat. They are to be used only with refrigerant vapor or gas, where they are typically installed on the top section of a pressure vessel, i.e. liquid receiver or suction accumulator.

53 and 56 series Pressure Relief Valves are suitable for use with ammonia, HCFC, and HFC refrigerants, and their associated oils, as well as other industrial fluids non-corrosive to steel, iron, and Teflon.

How it works

All Henry Technology Relief Valves are 100% tested and manufactured to guidelines as indicated in ASME Section VIII Division I. Every Relief Valve is calibrated to indicate a pre-determined set pressure, where the valve begins to allow gas or vapor to pass through. The valve will open to a full discharge within 10% over set pressure. After discharge Pressure Relief Valves will blow down and reseat once the pressure falls below the valve's set pressure.

Features

• NPT and SAE flare connections
• Valves fully open before 10% overpressure when taken from the average set pressure
• Reset pressure ranges typically 10-40% (blowdown) from pop pressure
• Valves bear individual serial numbers
• UV-1 pressure test reports available upon request
