We offer a variety of Danfoss 4-way reversing valves. Valves are used in systems such as heat pumps or AHU and reversible circulation chillers. They enable the refrigeration cycle to be reversed, changing from cooling in summer to heating in winter. The reversal is initiated by a small solenoid control valve that regulates the movement of the slider that diverts the flow of the refrigerant. The 4-way reversing valves are available for the following refrigerants: R407C, R134a, R404A, R22 and R410A and are produced in many connection diameters. Capacity ranges from 1.5 to 400 kW. UL and CE valves are certified.

Danfoss STF valve allows instant flow reversal and a low pressure drop due to the unique design of the internal components. The maximum operating pressure PS is 45 bar. Ambient temperature is from -20 to 55 °C. Valves available in the full capacity range up to 400 kW.

The application of 4-way reversing valves:

  • Heat pump systems
  • Chillers with reversible circulation
  • Compact air-conditioning units
  • Domestic air-conditioning equipment
