Description
The Trane VAL19427 is an OEM thermostatic expansion valve (TXV) engineered to deliver precise refrigerant flow control in Trane cooling and heat pump systems. By accurately metering refrigerant into the evaporator coil based on real-time superheat conditions, this valve helps maintain optimal system efficiency, protects the compressor from liquid slugging, and ensures consistent comfort performance across a wide range of operating conditions.
Designed as a direct OEM replacement, the VAL19427 eliminates the guesswork of aftermarket compatibility and is built to the same exacting tolerances as the original factory component. Whether you’re performing a warranty repair, a scheduled maintenance replacement, or a system restoration, this valve restores factory-specified refrigerant metering performance.
Key Features

- Compatible with applicable Trane air conditioning and heat pump equipment
Why Choose an OEM TXV?
Thermostatic expansion valves are critical refrigeration components — even minor deviations in flow rate or superheat setpoint can reduce system efficiency, increase compressor wear, and lead to premature equipment failure. The Trane VAL19427 is manufactured to OEM standards, ensuring the valve responds accurately to system demand and maintains the superheat range the equipment was designed to operate within.
Application
- Designed for use in compatible Trane residential and light commercial HVAC systems
- Ideal for service technicians performing TXV replacements on Trane equipment
- Consult Trane equipment documentation to confirm compatibility before installation
