Key Features and Advantages:
1. One-Touch Switching Between Cooling and Heating Modes: Precisely controls refrigerant flow direction, enabling rapid transition between cooling and heating modes to meet year-round operational demands and maximize unit utilization.
2. Precise OEM Compatibility—No Calibration Required: Fully matches the refrigerant flow and pressure parameters of Trane heat pump units; ready for immediate use following installation via brazing, ensuring zero compatibility issues.
3. Low Leakage, High Energy Efficiency: Features a Teflon sealing ring and a precision valve core, limiting internal leakage to ≤0.5%; this minimizes refrigerant loss and ensures stable energy efficiency for the unit.
4. High Reliability, Long Service Life: Constructed with a brass valve body and temperature-resistant seals, offering robust resistance to vibration and refrigerant corrosion; boasts a standard service life of ≥50,000 hours, making it ideal for long-term operation in equipment rooms.
5. Convenient Maintenance, Low Cost: Features a coil-less design where the coil can be replaced independently, eliminating the need to remove the entire valve assembly; this significantly reduces maintenance costs and minimizes system downtime.

Product Operating Principles:
1. Cooling Mode (Coil De-energized): The pilot valve returns to its spring-actuated home position; high-pressure refrigerant enters the chamber on the right side of the main valve spool, while the pressure on the left side is relieved, causing the spool to shift to the left. Ports D→C and E→S are connected; the compressor discharges refrigerant to the outdoor unit (condenser), while the indoor unit functions as the evaporator, thereby achieving cooling.
2. Heating Mode (Coil Energized): The electromagnetic coil actuates the pilot valve; high-pressure refrigerant enters the chamber on the left side of the main valve spool, while the pressure on the right side is relieved, causing the spool to shift to the right. Ports D→E and C→S are connected; the compressor discharges refrigerant to the indoor unit (condenser), while the outdoor unit functions as the evaporator, thereby achieving heating.
3. Reversing Control: Switching is achieved by energizing or de-energizing the electromagnetic coil, utilizing the pressure differential of the refrigerant to drive the movement of the valve spool. This mechanism enables sensitive and responsive reversing even under low pressure differentials, resulting in minimal pressure loss and high energy efficiency.
