York S1-025-33307-002 Reversing Valve

The York S1-025-33307-002 Reversing Valve is a critical 4-way pilot-operated component engineered specifically for York heat pump systems. This heavy-duty assembly features a 1/2" ODF suction line and 7/8" ODF discharge connections, facilitating precise refrigerant flow reversal to switch between heating and cooling cycles. Field-proven for high-pressure R-410A applications, this valve is primarily designed for B6HX series 15 SEER single-packaged units and B1HX060A06A models. The factory-included 24VAC solenoid coil (50/60Hz) ensures immediate response times and reliable magnetic shifting of internal slides, preventing "stuck valve" scenarios in extreme ambient conditions. For contractors performing a reversing valve replacement, this genuine OEM York HVAC part ensures physical port alignment and brazing compatibility without the need for field modifications or line re-piping.

• Factory-Integrated 24V Coil: Eliminates the need to source a separate solenoid, ensuring matched electrical impedance and reliable heat pump reversing operation.
• Standard ODF Connections: Features 1/2" x 7/8" copper sweat connections for rapid brazing and a leak-free HVAC refrigerant flow control seal.
• B6HX Series Specificity: Drop-in compatibility for York 15 SEER heat pumps, maintaining original factory performance specifications and efficiency ratings.
• Durable Slide Construction: Built to withstand high-cycle frequency and pressure differentials common in commercial and residential heat pump applications.
