FAQ
A: It controls the flow direction of refrigerant in heat pump and air conditioning systems, allowing switching between cooling and heating modes.
A: The solenoid coil actuates the pilot valve, which shifts the main valve to reverse the refrigerant flow. Without the coil, the reversing function cannot be performed.
A: Our valves are compatible with R22, R410A, R407C, R134a, R452A, R454A, and other common refrigerants. Special refrigerants can be supported upon request.
A: Standard coils are available in AC 220V 50/60Hz and AC 110V. Other voltage specifications (e.g., DC 24V) can be customized.
A: Yes, connection sizes, refrigerant compatibility, and coil specifications can be customized according to different system requirements.
A: It should be installed in the correct direction (according to IN/OUT markings), with proper brazing technique to avoid overheating the valve body or damaging the coil.
