Refrigeration heating circulator electronic expansion solenoid valve introduction

The electronic expansion valve is mainly used in refrigeration, air conditioning and heat pump systems to achieve automatic adjustment of refrigerant flow, so that the system can operate under optimal working conditions, and achieve rapid cooling or heating, precise temperature control and energy saving. It can also be used for pressure control of the suction line.
Features
Smaller installation space: low height, small size and light weight
Flow path optimization, lower noise
Fast action and energy saving
Suitable for reversible systems, such as heat pumps, two-way circulation, etc.
Ts series is more suitable for oil-free systems
