5244-series Henry Relief Valve, 1" MPT x 1" FPT

Henry 5244 straight-through brass relief valves, 1" MPT x 1" FPT

Applications

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

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.

Most states and municipalities which have refrigeration safety codes conform to the "American Standard Safety Code for Mechanical Refrigeration (ANSI/ASHRAE 15)". This code and ASME states that the Relief Valve setting is not to exceed the design working pressure of the vessel on which the Relief Valve is installed. The discharge capacity of relief valves varies with pressure setting. The discharge capacity required is based on the size of the vessel and the refrigerant used. See "Determining Minimum Required Discharge Capacity" section for more information, or contact Technical Support at 1-800-627-5148.

Whenever conditions permit, it is highly advisable to have the Relief Valve pressure setting (which must not exceed the design working pressure of the vessel) at least 25% higher than the normal operating pressure for the refrigerant used.
