Trane VAL10374 3-Ton R410A Thermostatic Expansion Valve 3/8" x 1/2" ODF

The Trane VAL10374 is a genuine OEM thermostatic expansion valve (TXV) engineered to regulate refrigerant flow in residential and light commercial HVAC systems. This valve is specifically designed for 3-ton cooling capacity applications using R410A refrigerant, ensuring optimal system performance and energy efficiency.

Key Features:

• 3-ton cooling capacity rating for precise system matching
• R410A refrigerant compatibility for modern HVAC systems
• 3/8" inlet x 1/2" outlet ODF (Outside Diameter Flare) connections
• Precision metering device that maintains proper superheat levels
• Protects compressor from liquid flooding and overheating
• Adjusts refrigerant flow based on real-time cooling demand
• Durable construction for long-term reliability
• Factory-calibrated for optimal performance

The thermostatic expansion valve works by monitoring temperature and pressure in the refrigeration cycle through a sensing bulb connected to the suction line. This feedback loop allows the valve to automatically modulate refrigerant flow into the evaporator coil, ensuring that all liquid refrigerant evaporates completely while preventing excess liquid from entering the compressor. This precise control maximizes heat exchange efficiency, reduces energy consumption, and extends equipment life. The VAL10374 features ODF flare connections for secure, leak-free installation and can be mounted in any position on the evaporator coil inlet.
