Henry Group® 5600-300

Description

The function of a pressure relief valve is to protect against overpressure. For safety reasons, excessive over-pressure in any part of the refrigeration system must be avoided. A typical application for a Henry Technologies pressure relief valve (PRV) is to protect a liquid receiver from being over-pressurised. In the event of a fire, any liquid refrigerant inside the receiver will evaporate resulting in an increase in pressure. The PRV will safely control this increase in pressure by venting the vapor from the receiver. Another application is to protect equipment from compressor over-pressure. Henry Technologies pressure relief valves are designed to discharge vapor and should not be used to vent liquid refrigerant. The valves are back-pressure dependent and are therefore required to discharge to atmosphere. The brass and stainless steel series valves are suitable for use with HCFC and HFC refrigerant gases. The stainless steel series valves are also suitable for ammonia. It is recommended to have a relief valve pressure setting at least 25% higher than the maximum system operating pressure. The PRV set pressure should not be higher than the design pressure (MWP) of the vessel.
