Carrier EF17BZ361 Reversing Valve

When you are dealing with a failing 4-way valve on a heavy-duty commercial unit, the Carrier EF17BZ361 Reversing Valve is the specific 8.5 ton reversing valve required to restore full heating and cooling functionality. As a direct OEM replacement reversing valve, the EF17BZ361 is engineered to swap out seamlessly for the discontinued EF17BG286 and S1-025-33379-001 models. This HVAC reversing valve with 24v coil eliminates the need for separate solenoid sourcing, ensuring the slide mechanism shifts reliably under high-pressure differentials common in 8.5-ton heat pump circuits. Featuring factory-authorized Carrier parts construction, this valve maintains the precise refrigerant flow control necessary to protect the compressor from liquid slugging during mode transitions. Whether you are performing a mid-season emergency repair or a planned system overhaul, using this heat pump reversing valve ensures the system meets its original SEER and HSPF performance ratings without the fitment headaches of universal alternatives.

• Direct OEM Compatibility: Specifically designed to replace obsolete EF17BG286 and S1-025-33379-001 units without piping modifications.
• Complete Assembly: Includes a factory-installed 24v solenoid coil for immediate integration into the existing control board circuit.
• High-Capacity Performance: Rated for 8.5 ton HVAC systems, providing the necessary orifice size for high-mass flow refrigerant applications.
• Reliable Changeover: Precision-machined internal slide ensures positive seating, preventing internal bypass leaks between suction and discharge lines.

Common Questions

Is the EF17BZ361 compatible with R-410A systems?
Yes, this valve is designed to handle the higher operating pressures of R-410A refrigerant found in 8.5-ton commercial heat pump applications.

Does this valve include the solenoid coil?
This model comes as a complete assembly including the 24v coil, so you do not need to pull the old coil from the failed valve.

What are the physical dimensions for fitment?
The unit measures approximately 10.35" x 9.25" x 5.25", adhering to the standard footprint of the 8.5-ton Carrier commercial line for easier brazing in tight cabinets.
