Daikin-McQuay 331761515 TXV Valve
For veteran HVACR contractors servicing residential and commercial systems, the Daikin-McQuay 331761515 TXV Valve is a specific factory-spec thermostatic expansion valve engineered for R410A refrigerant applications. Designed with 1-1/8" x 1-3/8" ODF sweat connections, this thermal expansion valve provides the heavy-duty flow capacity required for larger evaporator coils. Unlike generic alternatives, this OEM expansion valve ensures precise refrigerant metering, preventing liquid slugging and maintaining the correct superheat across varying load conditions. It is frequently utilized in high-capacity Daikin and McQuay air handlers and heat pump systems where maintaining a stable refrigerant charge and subcooling is critical for peak HVAC efficiency. The durable brass body and high-sensitivity sensing bulb are built to handle the higher operating pressures of R410A while resisting vibration-induced fatigue. When replacing a restricted or failed TXV, this 1-1/8 inch inlet valve offers a direct-fit solution to restore optimal performance without the need for extensive piping modifications or manifold adjustments.
Key Benefits:- Precise Superheat Control: Maintains exact refrigerant flow to protect the compressor and maximize evaporator efficiency.
- OEM Compatibility: Exact replacement for Daikin-McQuay 331761515, ensuring identical performance to the original installation.
- Robust R410A Design: Specifically calibrated for high-pressure R410A systems with 1-1/8" and 1-3/8" tubing.
- Enhanced Reliability: Heavy-duty construction minimizes the risk of diaphragm failure or sensing bulb leakage in demanding environments.
What are the connection sizes for this TXV?
This valve features a 1-1/8 inch ODF inlet and a 1-3/8 inch ODF outlet (sweat connections).
Is the Daikin-McQuay 331761515 compatible with R-22?
No, this valve is strictly calibrated for R410A refrigerant and should not be used in R-22 or R-407C systems.
How do I prevent damage during installation?
Professional technicians should always wrap the valve body in a wet rag or heat-sink paste during brazing and flow nitrogen to prevent internal carbon buildup.
