Trane VAL19947 TXV
The Trane VAL19947 is a precision-engineered R410A 3 Ton TXV designed for high-performance refrigerant metering in residential and light commercial evaporator coils. This thermostatic expansion valve maintains optimal superheat control, ensuring the evaporator is properly fed under fluctuating load conditions to prevent compressor floodback and maximize system efficiency. Built for high-pressure R410A refrigerant systems, it features a 3/8" ODF inlet and 1/2" ODF outlet with an external equalizer connection to compensate for pressure drops across the coil. As a genuine OEM Trane expansion valve, the VAL19947 provides a reliable drop-in solution for 3-ton air conditioning and heat pump units, holding a working pressure rating up to 500 PSI. For technicians performing an HVAC TXV replacement, this valve is essential for restoring factory-spec cooling capacity and SEER ratings. Its durable brass construction and balanced port design allow for stable operation across a wide range of ambient temperatures, delivering the consistent performance required in demanding field environments.
Key Benefits:- Precise Refrigerant Metering: Automatically adjusts flow to maintain the targeted evaporator superheat, protecting the compressor from liquid slugging.
- Optimized Energy Efficiency: Maximizes heat exchange across the coil, helping the system achieve its rated HVAC efficiency.
- OEM Compatibility: Designed specifically for Trane and American Standard 3-ton air conditioner and heat pump systems for a perfect fit.
- External Equalization: Provides accurate pressure sensing at the evaporator outlet, ensuring responsive valve modulation even in high-pressure drop configurations.
- Robust Construction: Engineered to withstand high-pressure R410A environments with a 500 PSI maximum operating limit.
- Is the Trane VAL19947 compatible with R22 systems? No, this valve is specifically calibrated for the pressure-temperature characteristics of R410A refrigerant and should not be used in R22 applications.
- Does this TXV require an external equalizer line? Yes, the VAL19947 features an external equalizer connection. This line must be piped to the suction line near the sensing bulb for proper operation.
- Can this valve be used for 2-ton or 4-ton systems? This model is sized for a nominal 3-ton capacity. Using an incorrectly sized TXV can lead to hunting, poor superheat control, and potential system damage.
