4-Way Reversing Valve
Sanhua Reversing Valves switch between cooling and heating mode by changing the flow of the refrigerant. The solder connection at the pilot tube and valve allows for increased reliability and low leakage probability. The Reversing Valves are compatible with all common HCFC and HFC refrigerants and are UL recognized with a maximum operating pressure of 650 psig.
