ClimateMaster 33B0006N13 Expansion Valve

The ClimateMaster 33B0006N13 Expansion Valve is a high-precision, 1-ton thermostatic expansion valve (TXV) engineered for residential and commercial geothermal heat pumps and water-source HVAC systems. As the direct OEM replacement for 33B0013N08, this 1 ton expansion valve is a critical component for technicians looking to restore factory-spec refrigerant metering and superheat control. It is factory-set for R-410A refrigerant and utilizes a bi-metal construction for enhanced durability in fluctuating temperature environments.

This geothermal TXV operates by modulating the flow of refrigerant into the evaporator coil based on cooling demand, ensuring the system maintains a target superheat. For professionals troubleshooting low suction pressure or erratic superheat readings, replacing the older N08 model with this updated N13 unit ensures seamless compatibility with ClimateMaster heat pump parts. Its compact design allows for efficient installation in tight cabinets found in 1-ton packaged units, providing the reliable pressure drop necessary for optimal heat exchange and compressor protection.

• Direct OEM Replacement: Replaces outdated or failed part 33B0013N08 with the latest factory specifications.
• Precise Superheat Control: Maintains consistent evaporator outlet conditions to prevent liquid floodback and protect the compressor.
• R-410A Compatibility: Specifically designed for the pressure ranges and performance characteristics of R-410A systems.
• Durable Bi-Metal Body: Built to withstand the high-vibration environment of modern water-source heat pumps.

Is the 33B0006N13 interchangeable with other 1-ton expansion valves?
This valve is specifically an updated version for the 33B0013N08 and 33B0006N13. To ensure proper metering and superheat performance, it should only be used as a direct replacement in compatible ClimateMaster 1-ton units.

Can I adjust the superheat setting on this valve?
While many technician-grade TXVs are adjustable via a bottom nut, this specific ClimateMaster OEM valve is typically factory-set to maintain optimal superheat for the designated tonnage. Verify the specific unit requirements before attempting adjustment.

Does this valve include the sensing bulb and capillary?
Yes, this is a complete thermostatic expansion valve assembly. Always ensure the sensing bulb is properly insulated and securely strapped to the suction line for accurate temperature sensing.
