Summary

 

    DHF 4-way reversing valve, the key part of the heat pump air conditioner, diverts the direction of the refrigerant flow under the electromagnetism of the pilot valve to supply either heating in winter or cooling in summer to the conditioned place. The character of the design of the DHF series is twice-opening, the diversion is controlled by the pilot valve, ensuring the high reliability of operation.
