ClimateMaster 33B0006N16 TXV

The ClimateMaster 33B0006N16 TXV is a precision-engineered thermal expansion valve designed for high-performance refrigerant metering in water-source heat pumps and geothermal systems. Built with a 3/8" ODF connection and a 30-inch capillary tube, this OEM component ensures accurate superheat control across varying thermal loads. The integrated 15% bleed port allows for pressure equalization during the off-cycle, easing compressor startup and reducing mechanical stress on the system. As a veteran-grade HVAC replacement part, it maintains the precise refrigerant flow control required to prevent liquid slugging and evaporator freeze-ups in demanding ClimateMaster Tranquility units.

Engineered for technical reliability, the 33B0006N16 handles a wide range of entering water temperatures, making it a critical geothermal TXV for contractors troubleshooting low suction pressure or erratic sub-cooling. Unlike generic alternatives, this ClimateMaster expansion valve is calibrated to match original equipment specifications, ensuring seamless field installation and long-term system stability. Replacing a restricted or non-responsive valve with this genuine HVAC thermal expansion valve restores optimal heat transfer efficiency and protects the compressor from high-superheat overhead.

• Optimized Refrigerant Metering: Delivers precise liquid flow to the evaporator for consistent superheat levels.
• 15% Bleed Port: Facilitates off-cycle pressure balancing to protect the compressor during startup.
• OEM Construction: Features a durable 30" capillary and 3/8" ODF sweat connections for a leak-free, professional fit.
• Geothermal Compatibility: Specifically designed to handle the unique pressure differentials of water-to-air heat pump systems.

• How do I confirm if the 33B0006N16 has failed? Technicians should check for low suction pressure accompanied by high sub-cooling and high superheat; if shifting the bulb temperature does not affect pressure, the valve is likely non-responsive.
• Does this TXV support R-410A systems? Yes, this valve is engineered for the high-pressure environments typical of modern ClimateMaster refrigerant circuits.
• Is this an external or internal equalizer valve? This model is designed for internal pressure sensing consistent with ClimateMaster's specific coil header configurations.
