Mitsubishi Electric E22A54961 4-Way Valve

The Mitsubishi Electric E22A54961 4-Way Valve is an essential part of HVAC systems, especially heat pump systems. Its primary application as a 4-way valve is to change the direction of refrigerant flow in a heat pump between the indoor and outdoor units. When in cooling mode the valve manages refrigerant circulation to remove heat from inside compartments and expel it to the outside environment. However, in heating control mode, the flow is in the opposite direction to allow heat to be pulled from the outside and across the system.
