Electronic Expansion Valves

Place of Origin:	Shanghai

DPF-1 2000pulse electronic expansion valve is a kind of speed-down style valve, which includes all good peculiarities that a motor-driven electronic expansion valve has. Its step motor transfers power through speed-down gear group and adjusts the rising process of valve pin with bellows. The function of gear's slowing down increases largely output torque so that the small electromagnetic power could obtain the plenty output moment.

Its full open pulse is 2,000. Its adjustment is more accurate and the performance is better. The pulse electricity driver and gear group can be easily split from valves with different diameter orifice. It can meet the needs of controlling flux in different range, provided the valve is changed.
