SHF 4-Way Reversing Valve series G

ref. SHF 4-Way Reversing Valve series G

SHF (G) series four-way valves are especially applicable for heat pump systems including high-end and highefficient unitary and room air conditioners to realize switching between cooling mode and heating mode by changing the flow path of refrigerant.

Air conditioning Heat Pump


  • Power saving: nearly zero energy consumption with bi-stable coils
  • Energy saving: stainless steel used for main parts, low heat loss with reduction of precious metals which reduces energy consumption
  • Excellent anti-vibration performance: the pilot valve has good anti-system abnormal recoil ability and action performance which is welded securely to the main valve
  • Excellent action performance at low temperature: optimized design of main valve parts
  • Only applicable for DC or bi-stable control, not for AC control.

General specifications

  • Applicable refrigerant: R22, R407C, R410A etc.
  • Applicable medium temperature: -30ºC (-22ºF) ~ +120ºC (248ºF)
  • Applicable ambient temperature: -30ºC (-22ºF) ~+50ºC (122ºF)
