By switching the flow of refrigerant, the air conditioner can incorporate the functions of cooling in summer and heating in winter together. The 4-way reversing valve consists of main valve, pilot valve, and solenoid coil. The valve is a part of the refrigerant circuit of compressor, condenser, indoor heat exchanger and other components. The pilot valve controls the main valve through pressure difference to change the direction of refrigerant flow and further switch between heating and cooling. The changeover is reliable and flexible. It can be applied in heat pump systems like central, unitary, room air conditioner and so on. 2. Characteristics： 1）Long product line covers 1~16USRT； 2）Compatible with refrigerants including R22、R134a，R407C、R410a,etc.； 3）Energy efficiency：power consumption 20% lower ●Bi-stable 4-way reversing valve can work as requested even after being deenergized by optimizing the design solenoid coil. No power is consumed except shifting. ●After the optimizing the material of stainless steel products, the power consumption can be reduced by 5%. 4）Environment protection：Environment friendly production methods are adopted.
