Climatemaster C33B0006N20 Thermal Expansion Valve Txv

Product Description

The CLIMATEMASTER C33B0006N20 is a thermal expansion valve (TXV) designed to regulate refrigerant flow into the evaporator coil with precision. The valve senses the temperature and pressure of refrigerant leaving the evaporator and adjusts flow to maintain the correct superheat level. This prevents liquid refrigerant from reaching the compressor, protecting the system from damage. Controlling superheat also supports efficient heat transfer, which sustains the cooling and heating capacity of the system. Licensed HVAC technicians install this component as part of routine refrigeration circuit service or system repair.

The C33B0006N20 is suited for HVAC refrigeration circuits where precise refrigerant metering is required. It supports stable system operation across both cooling and heating modes, making it applicable to split systems, heat pumps, and similar refrigerant-based equipment. This valve is a service replacement part intended for installation by qualified refrigeration technicians working on commercial or residential HVAC equipment.

Key Features

• Regulates refrigerant flow into the evaporator coil for precise superheat control
• Protects the compressor by preventing liquid refrigerant carryover
• Supports efficient heat transfer in both cooling and heating modes
• OEM part number ensures fitment accuracy for CLIMATEMASTER equipment

Compatibility

Designed as an OEM-style replacement TXV for CLIMATEMASTER HVAC systems requiring refrigerant flow control at the evaporator inlet.

Installation Notes

Installation must be performed by an EPA Section 608 certified HVAC technician. The refrigerant circuit must be recovered and the system depressurized before removing or installing the valve. Follow all applicable mechanical codes and the equipment manufacturer service documentation when brazing or connecting refrigerant lines. Verify superheat settings after installation before returning the system to operation.
