PRESSURE REGULATING VALVES Type HPRGENERAL DESCRIPTION•Type HPR can control the condensing pressure corresponding to the change in the outside temperature, and prevents the condensation pressure decrease in the control in winter, also steady throughout the year control is possible.•This product properly maintains the inlet pressure of the expansion valve and prevents the decrease in the refrigeration capacity.•Suitable for refrigeration systems with hot gas defrosting.SPECIFICATIONSMax.Working Pressure: 2.9MPa {29kgf/cm2} (R22, R134a, R404A, R407C)4.17MPa {41.7kgf/cm2} (R410A)Airtight Test Pressure: 3.5MPa {35kgf/cm2} (R22, R134a, R404A, R407C)4.17MPa {41.7kgf/cm2} (R410A)Fluid Temperature: to 125℃TYPE NUMBER SELECTION・Flare type is produced only 5/8 and 1/2.・R410A type is produced only 5/8 and 1/2.Catalog No.Port size (mm)ConnectionFactory Setting (MPa) Wt.
