McQuay 106697007 Valve

The McQuay 106697007 is a precision-engineered Thermal Expansion Valve (TXV) designed for high-performance R-22 refrigerant systems. Rated for 3-ton capacity, this field-proven component features 1/2 x 1/2 ODF (Outside Diameter Female) solder connections, ensuring a leak-resistant interface within the liquid line. The inclusion of a 1/4" External Equalizer (EE) allows the valve to accurately monitor evaporator outlet pressure, compensating for pressure drops across the coil to maintain optimal superheat. This balance prevents compressor liquid slugging while maximizing evaporator efficiency. As a genuine OEM replacement part for Daikin Applied and legacy McQuay air handling units and chillers, the 106697007 provides a drop-in solution for contractors performing critical repairs. Its robust construction is built to withstand the rigorous duty cycles of commercial HVACR applications, ensuring stable refrigerant metering and consistent system pressures across varying thermal loads.

• Precise Superheat Control: Maintains exact refrigerant flow to protect the compressor from liquid carryover.
• OEM Compatibility: Exact dimensional match for McQuay 106697007, reducing time on site for field retrofits.
• External Equalization: 1/4" EE line Provides accurate feedback for systems with high-pressure drops across the evaporator.
• Durable ODF Connections: High-quality copper stubs allow for clean, reliable brazing into the refrigerant circuit.

What is the tonnage rating for this TXV?
This valve is specifically calibrated for 3-ton R-22 refrigeration or air conditioning systems.

Does this valve use an internal or external equalizer?
The 106697007 uses a 1/4" external equalizer for more precise sensing of evaporator pressure.

Is this part compatible with R-410A systems?
No, this expansion valve is designed specifically for R-22 pressure-temperature curves and should not be used with R-410A.
