Daikin-McQuay 300047538 TXV
Ensure precise refrigerant metering and system efficiency with the Daikin-McQuay 300047538 TXV. This high-capacity 4-ton thermostatic expansion valve is a critical component for maintaining the correct superheat and protecting the compressor from liquid slugging. Featuring 5/8" x 5/8" ODF connections, this valve allows for secure, leak-resistant brazing into the liquid line and evaporator inlet. The integrated 60" capillary tube provides the necessary reach for flexible sensing bulb placement, ensuring accurate temperature feedback even in complex air handler or evaporator coil configurations. Designed as a direct OEM replacement part, the 300047538 is engineered to withstand the rigorous demands of commercial and residential HVACR applications. As an HVAC expansion valve, it optimizes the refrigeration cycle by modulating flow based on cooling demand, preventing evaporator freeze-ups and ensuring consistent indoor comfort. Rely on this Daikin McQuay 300047538 for professional-grade reliability and exact system compatibility.
Key Benefits:- Precise Refrigerant Control: Modulates flow to maintain optimal superheat and prevent compressor damage.
- OEM Compatibility: Genuine Daikin-McQuay 300047538 ensures exact fitment and performance standards.
- Robust Connectivity: 5/8" ODF solder connections provide a reliable, permanent seal for 4-ton systems.
- Extended Reach: The 60-inch capillary tube allows for versatile sensing bulb positioning.
- High System Efficiency: Maximizes heat exchange across the evaporator coil to reduce energy consumption.
What are the signs that my 4-ton TXV needs replacement?
Common indicators include the evaporator coil icing up, the compressor running high discharge pressures, or the system failing to maintain set temperatures despite a correct refrigerant charge.
Can I use this valve on a system with a different tonnage?
No, this valve is fixed for a 4-ton capacity. Installing an incorrectly sized expansion valve will lead to improper refrigerant metering, potentially causing system failure or efficiency loss.
Is the sensing bulb included with the 300047538 TXV?
Yes, this model features a 60" capillary tube and attached sensing bulb designed to monitor the suction line temperature for real-time flow adjustment.
