Trane VAL8641 TXV
The Trane VAL8641 TXV is a high-precision 3-ton thermal expansion valve engineered specifically for R410A refrigerant systems. This OEM Trane expansion valve is a critical metering device that regulates refrigerant flow into the evaporator coil, maintaining precise superheat levels and safeguarding the compressor from liquid slugging. Built for durability in demanding residential and light commercial applications, the VAL8641 features a nominal capacity of 36,000 BTU/hr and utilizes sweat ODF connections—measuring 5/16" inlet x 1/2" outlet—to ensure a leak-free, high-integrity joint during brazing. The non-bleed port design prevents pressure equalization during the off-cycle, making it an ideal candidate for systems requiring high SEER efficiency and strict pressure control. Whether you are performing a field repair or a full coil replacement, this R410A TXV replacement provides the mechanical reliability veteran contractors expect from the Trane VAL8641 series.
Key Benefits:
- Precise Superheat Regulation: Optimized for R410A refrigerant to ensure maximum heat transfer across the evaporator.
- OEM Compatibility: Exact replacement for Trane VAL8641 and VAL08641, ensuring zero-clearance fitting issues on 3-ton coils.
- Durable Construction: Rated for a Maximum Working Pressure (MWP) of 450 PSI to handle high-pressure modern cooling cycles.
- Non-Bleed Port: Enhances system efficiency by maintaining a pressure differential during off-cycles.
- Standard Connection Sizes: Features a 5/16" ODM x 1/2" ODF configuration for standard liquid and suction line compatibility.
Common Questions:
Is the Trane VAL8641 compatible with R22 systems?
No, this valve is specifically calibrated for the pressure-temperature characteristics of R410A. Using it with R22 will lead to improper metering and potential compressor failure.
What are the physical dimensions for installation planning?
The valve body is approximately 4.8 inches in length with a 30-inch capillary tube, providing ample reach for sensing bulb placement on the suction line.
Does this valve require an external equalizer?
The VAL8641 is designed to match specific Trane and American Standard coil configurations; always check the specific evaporator model to determine if an external equalizer line port is required for your installation.
