Climatemaster C33B0020N02 Txv Expansion Valve

Product Description

The CLIMATEMASTER C33B0020N02 is a genuine OEM thermostatic expansion valve (TXV) designed for use in geothermal heat pump systems. The TXV meters refrigerant flow into the evaporator coil, maintaining the correct superheat level for efficient system operation. Identified by the configuration code CBBIZE 3GA BP15 30CAP, this valve is a direct OEM replacement that maintains factory refrigerant metering performance. Licensed HVAC technicians handling refrigerant-side repairs will find this part a straight drop-in for the failed or degraded original valve.

This TXV is intended for geothermal water-source heat pump applications where precise refrigerant metering is critical to system efficiency and compressor protection. Geothermal systems cycle refrigerant through both heating and cooling modes, placing consistent demand on the expansion device. Using a genuine OEM valve ensures the metering characteristics match the original equipment design rather than relying on aftermarket substitutes that may not match flow capacity or bulb charge specifications.

Key Features

• Genuine OEM CLIMATEMASTER replacement part — maintains factory refrigerant metering performance
• Configuration code CBBIZE 3GA BP15 30CAP indicates specific orifice sizing and bulb charge for this application
• Designed for geothermal water-source heat pump refrigerant circuits
• Direct replacement fit — no modification required for OEM installation positions

Compatibility

Designed as an OEM-style replacement TXV for CLIMATEMASTER geothermal heat pump systems requiring a C33B0020N02 expansion valve.

Installation Notes

TXV replacement is a refrigerant-side repair that must be performed by an EPA Section 608 certified HVAC technician. Recover all system refrigerant before opening the refrigerant circuit. After installation, evacuate the system to the manufacturer-recommended vacuum level before recharging with the specified refrigerant type and weight. Verify superheat readings at startup to confirm correct valve operation.
