Description

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.
