Application

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.

Features
  • Low noise & high control precision
  • Bi-directional flow
  • Low power consumption & wide flow regulation range
  • Superior self-lubricating thread trasmission
  • Application spectrum has extended into system under potentially explosive conditions
  • Plastic packaging anti-corrosion coil
  • Advanced and highly reliable welding
  • Good actuating performance
  • Lightweight and compact construction
