DRVB series large capacity cross-type four-way electromagnetic reversing valves are applicable for large-scale heat pump systems and ice machines and other equipment to realize the switching between cooling and heating modes by changing the flow direction of refrigerants, which is realized by the on/off control of the external pilot valve solenoid coil, leading the flow direction of the external high pressure gas in the valve body. As a result, the pressure diference between the both ends of piston is changed so that the piston moves inside the valve body, which changes the location fitting between the piston flow passage and the four connecting pipes outside the valve body.
● X-cross design ensures big flow area and low pressure drop;
● Stability and reliability ensured by adopting a small 4-way valve as pilot valve;
● Built-in self-lubricating bush;
● Special material of seal ring ensures the valve's applicability to all common refrigerants;
● Copper pipeline connection needed for installation.
