Gree 430004032 4-Way Reversing Valve for Heat Pump Systems

The Gree 430004032 is a 4-way reversing valve designed for use in Gree heat pump mini-split and packaged terminal air conditioner/heat pump (PTAC/PTHP) systems. This critical component enables the system to switch between cooling and heating modes by reversing the direction of refrigerant flow through the unit.

Key Features:

• OEM replacement part for Gree MULTI18HP230V1CO and MULTI24HP230V1CO outdoor units
• Compatible with various Gree heat pump systems including packaged terminal units and mini-split outdoor condensers
• Electrically actuated valve controlled by the system's main control board via solenoid coil (part number 4300040045, sold separately)
• Engineered for high-pressure R-410A refrigerant operation
• Used in conjunction with 4-way valve assembly components for complete installation

This valve is part of the refrigerant circuit in Gree outdoor units, working alongside the compressor, electronic expansion valves, and gas-liquid separator to provide efficient year-round climate control. The valve shifts position when energized to redirect hot gas flow, allowing the system to operate in either air conditioning or heat pump mode.
