Electromagnetic Four-way Reversing Valve
<!--<$[标题]>begin-->Electromagnetic Four-way Reversing Valve<!--<$[标题]>end-->

The electromagnetic four-way reversing valves are applicable for residential airconditioners, VRVs, module units, unit machines, heat pumps and other refrigerationsystems. They are used to realize switching between cooling mode and heating modeby changing the flow path of refrigerant.

FEATURES

•  Diversified designs with brass and stainless steel. Applicable for fixed frequency, variable frequency, fixed frequency high temperature and variable frequency high temperature systems.

•  High strength, light weight, good vibration resistance, low heat loss and high energyefficiency.

•  Connection tubes, valve body and seat are made of stainless steel.

•  Reliable stainless steel valve welding, connection tube in a copper sleeve, easy to welding .

•  Optional energy efficient coils

 

OPERATION CONDITIONS

•  Applicable Refrigerants: R410A, R32, R134a, R404A R507, R290, R407C,R22( As forR290 please confirm before placing orders.)

•  Maximum Operation Pressure:4.5 MPa

•  Ambient Temperature:-30°C~+55°C

•  Relative Humidity:<95%
