Trane 4AYTXVH3G2436A TXV
The Trane 4AYTXVH3G2436A TXV is a critical OEM thermal expansion valve engineered for precision refrigerant metering in 3-ton R410A cooling systems. Designed for 4GXC, 4MXC, and TMM4 indoor coils, this non-bleed, externally equalized valve maintains optimized superheat levels by adjusting flow based on evaporator temperature. By preventing liquid slugging and ensuring the evaporator coil is utilized to its full capacity, this component is essential for maintaining the efficiency of 14 SEER or higher split systems and heat pumps. The kit features a robust brass body with 3/8-inch mechanical fittings and a 3/4-20-2B UNEF thread connection, allowing for a reliable, leak-free installation in demanding residential or light commercial environments. For field replacements involving reciprocating compressors, technicians should verify if a hard-start kit is required to overcome higher head pressures during startup. This genuine Trane expansion valve ensures your system operates within manufacturer specifications, balancing performance with long-term mechanical reliability.
Key Benefits- Precise Flow Control: Maintains proper superheat to protect the compressor from liquid floodback.
- System Efficiency: Required for 14 SEER compliance and optimal performance in R410A systems.
- High Compatibility: Direct OEM replacement for Trane and American Standard 4MXC and TMM4B coils.
- Durable Construction: Built with high-grade copper and brass to withstand high-pressure HVAC environments.
- Optimized Cooling: Ensures maximum heat transfer across the evaporator for consistent indoor comfort.
Is the 4AYTXVH3G2436A a non-bleed or bleed-type valve?
This is a non-bleed TXV, which provides a positive shut-off and maintains pressure in the liquid line during the off-cycle.
Can this valve be field-installed on older R22 coils?
This kit is specifically calibrated for R410A refrigerant. While it can be used to convert compatible coils, the refrigerant type must always match the outdoor unit’s requirements.
What are the connection sizes for this 3-ton TXV?
The valve utilizes a 3/8" inlet and outlet with standard mechanical fittings for streamlined installation.
