Description
The Trane VAL19629 is an OEM thermostatic expansion valve (TXV) engineered for reliable, precise refrigerant flow control in 3-ton HVAC systems. Designed as a direct replacement for compatible Trane equipment, this valve meters liquid refrigerant into the evaporator coil to maintain optimal superheat levels — maximizing system efficiency, protecting the compressor, and extending overall equipment life.
Key Features
- OEM Trane replacement TXV for accurate, drop-in fitment
- Rated for 3-ton system capacity
- 3/8″ inlet connection for liquid line hookup
- 1/2″ outlet connection for evaporator coil feed
- Maintains consistent superheat for peak system performance
- Protects the compressor from liquid slugging and overheating
- Engineered for durability and long service life in residential and light commercial applications
Why Choose a TXV?
Thermostatic expansion valves automatically adjust refrigerant flow in response to changing load conditions, unlike fixed-orifice metering devices. This dynamic control improves energy efficiency, reduces compressor wear, and ensures consistent cooling comfort across a wide range of operating conditions.
