Description
The Trane VAL12849 thermostatic expansion valve (TXV) is designed to regulate refrigerant flow in HVAC systems with a nominal capacity of 3 tons. Engineered for use with R-410A refrigerant, this valve maintains proper superheat by adjusting refrigerant flow based on system demand at the evaporator. The integrated bleed port allows for pressure equalization during off cycles, supporting smoother startups and improved system performance. Built for compatibility with Trane equipment, this TXV is suitable for residential and light commercial air conditioning applications.
