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.

The H-type thermal expansion valves for auto air-conditioners are such valves which expand on heat by interiorly temperature sensing and exteriorly balancing. They feature a sensitivity and reliability in temperature sensing, firmness against the pressure dropping-down with the evaporator, vibration resistance, easiness of regulating etc.. Apart from reference to American, Japanese and other international auto standards, our QRFWH serial expansion valves also represent advanced technologies and special characteristics.
