PRESSURE REGULATING VALVES - Type HPR
 
GENERAL 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.

APPLICATION EXAMPLE 
• Condensation pressure regulating valve type HPR. This product can control the condensing pressure corresponding to the change in the outside temperature, and prevents the condensing pressure decrease in the control in the 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 use in refrigeration systems with hot gas defrosting and in extremely cold region.
