Carrier EF17BZ113 Reversing Valve

The Carrier EF17BZ113 Reversing Valve is a critical 4-way heat pump component engineered for precise refrigerant flow reversal in residential and light commercial HVAC systems. This 24V reversing valve features a 1/2" suction and 5/8" discharge configuration, ensuring optimal pressure drop characteristics and thermal efficiency during cycle transitions. As the direct EF17BZ113 replacement for EF17BZ115, this valve maintains OEM specifications for seamless integration into existing Carrier heat pump reversing valve assemblies. For technicians troubleshooting Carrier heat pump not switching modes, this unit provides the necessary reliability for solenoid-actuated shifting. The robust slide bracket design minimizes internal bypass leakage, protecting the compressor from liquid slugging while maintaining high EER ratings. When performing a reversing valve replacement, ensure proper heat sinking during brazing to preserve the internal Teflon seals and maintain the 4-way pilot valve integrity for long-term operational stability.

• Direct OEM Compatibility: Engineered for precision fitment as a factory-authorized replacement for the EF17BZ115 model.
• High Thermal Stability: Built to withstand the high-temperature discharge gas common in modern high-SEER heat pump cycles.
• Optimized Pressure Differential: Designed to shift reliably even under low pressure differentials, preventing mid-shift stalls.
• Standard 24V Actuation: Compatible with standard 24VAC control circuits for universal interface with most residential thermostats and defrost boards.

Is the solenoid coil included with the EF17BZ113?
This model is typically supplied as the valve body; reuse the existing 24V coil or verify the solenoid requirements based on the specific air conditioner or heat pump service manual.

What is the orientation requirement for installation?
The valve should be installed following the manufacturer’s flow direction arrows, typically with the suction line oriented horizontally or as per the original equipment layout to prevent oil trapping.

Can this valve be used with R-410A systems?
Yes, the EF17BZ113 is rated for high-pressure synthetic refrigerants including R-410A and R-22, provided the line sizes match the 1/2" x 5/8" specifications.
