Daikin-McQuay 106489122 TXV
The Daikin-McQuay 106489122 TXV is a precision-engineered 5-ton thermal expansion valve designed for mission-critical refrigerant flow control in high-capacity HVAC systems. Built for R-410A refrigerant applications, this OEM replacement part features a 5/8" x 1/2" ODF sweat connection and a 60-inch capillary tube, ensuring accurate superheat regulation across varying load conditions. For technicians servicing Daikin commercial air conditioning units or McQuay chillers, maintaining the correct evaporator superheat is essential to protect the compressor from liquid slugging while maximizing heat transfer efficiency. The robust balanced port design allows this valve to perform reliably even under fluctuating head pressures, providing stable operation in both residential and industrial environments. When diagnosing poor cooling or erratic suction pressures, swapping in this genuine 106489122 expansion valve ensures the system returns to its original factory performance specifications without the risk of compatibility issues inherent with universal aftermarket components.
Key Benefits- Precise Refrigerant Metering: Optimized for 5-ton systems to maintain consistent evaporator temperatures and prevent compressor damage.
- OEM Compatibility: Exact drop-in replacement for Daikin and McQuay part number 106489122, ensuring proper fitment and performance.
- Durable Construction: High-grade brass body with a 60" capillary tube designed to withstand high-vibration commercial environments.
- Sweat ODF Connections: Standard 5/8" inlet and 1/2" outlet sizes allow for secure, leak-free brazing into the liquid line.
- R-410A Optimized: Specifically calibrated for high-pressure R-410A systems to ensure accurate flow modulation.
Is the sensing bulb included with this TXV?
Yes, this thermal expansion valve includes the integral 60-inch capillary tube and power assembly with the sensing bulb for accurate temperature feedback from the suction line.
Can I use this valve on a 4-ton system?
This valve is specifically rated for 5-ton capacities. Using an oversized or undersized TXV can lead to hunting, floodback, or poor oil return; always verify your equipment's tonnage before installation.
What is the proper way to protect this valve during brazing?
To prevent internal damage to the needle and seat, always use a wet rag or thermal blocking heat paste on the valve body during the brazing process to keep temperatures below 250°F.
