Electronic Expansion Valve VPF

Electronic Expansion Valve VPF 1

Electronic Expansion Valve VPF

Electronic expansion valve is mainly used in refrigeration, air-conditioning and heat pump systems to achieve automatic adjustment of refrigerant flow, make the system operate under the best conditions, and achieve rapid cooling or heating, precise control Moderate energy saving and other purposes. It can also be used for pressure control of the suction pipe.

Features

  • Energy saving thanks to veryprecise capacity control: Up to 3800 steps
  • Internal Tightness like a solenoid valve
  • Optimized flow path design for noise reduction
  • Applicable for reversible systems like heat pumps: bidirectional flow
  • Corrosion resistant design, long lifetime, high realiability
  • Compact design
  • Models with integrated sight glass are available

Place of origin:Made in China, export to worldwide.
