DSF Series for HP & HT

APPLICATION

DSF series 4-way reversing valve for HT & HP application is a special variant, which meets requirements of new refrigerants, and is suitable for application of all kinds of heat pump systems undemore extreme conditions. it changes the flow path of refrigerants reliably by controlling the pilotvalve to switch the mode between cooling and heating.

DRVB Series

APPLICATION

DRVB series large capacity cross-type four-way electromagnetic reversing valves are applicablefor large-scale heat pump systems and ice machines and other equipment to realize the switchingbetween cooling and heating modes by changing the flow direction of refrigerants, which isrealized by the on/off control of the external pilot valve solenoid coil, leading the flow direction ofthe external high pressure gas in the valve body. As a result, the pressure diference between theboth ends of piston is changed so that the piston moves inside the valve body, which changes thelocation fitting between the piston flow passage and the four connecting pipes outside the valve body.
