Electronic Expansion Valve

DPF Series


DPF Series electronic expansion valve is mainly composed of step motor and valve needle with magnetic rotor, driven by coil which receives pulse signals from controller. The transmission screw converts the rotary motion of the rotor component into the axial linear motion of the valve needle to regulate the flow area of the valve port, adjusting the refrigerant flow rate.
