4-Way Reversing Valve

4-Way Reversing Valve

Features & Applications

The 4-way reversing valve is a control component used in refrigeration and air conditioning systems that enables switching between cooling and heating modes by reversing the refrigerant flow direction. It is a key component in heat pump systems, as it reverses the cycle direction, allowing the evaporator and condenser functions to interchange.

Technical Features
  • Robust body design resistant to high pressure and temperature variations
  • Optimized flow path design for quiet and vibration-free operation
  • Fast and stable switching performance via electrically actuated solenoid coil control
  • Compatible with a wide range of refrigerants such as R410A, R32, R134a, CO₂, and others
  • Internal valve design preventing leaking minimizes energy losses
Application Areas
  • Heat pump systems
  • Reversible split air conditioners and VRF systems
  • Commercial and residential HVAC units
  • Industrial heat recovery systems
  • Special transitive  systems  between cool and hot rooms
