1、 Condensing pressure control valve Condensing pressure control valve PRV series PRV series shanghai kaobo machinery electrical equipment co., ltd http:/www.sh- samanthash- Product description PRV series condensing pressure control valves are normally installed on the coolant pipe of a condenser (usu
2、ally on the entrance). Because the PVR series can adjust the flow rate of the coolant by sensing the refrigeration recycling pressure according to changes in condenser pressure, the result is a significant improvement in coolant use efficiency. In this manner, PRV series vales are able to provide on
3、 demand cooling. When condenser pressure is raised in the compressor, the valves will be opened automatically so that there is more coolant moved into the condenser to quicken the refrigeration cooling process. Alternately, coolant levels will become lower with the pressure falling and valves being
4、closed automatically, therefore the condensing pressure is kept within a normal operating range. PRV series valves adjusting method: The adjusting lever can be rotated when regulating, the controlling pressure raises by rotating clockwise, alternately by rotating counter clockwise the pressure drops
