Description
The Trane VAL9111 is an OEM thermostatic expansion valve (TXV) engineered specifically for R-410A refrigerant systems at a 3-ton capacity. Featuring an external equalizer port, this valve delivers accurate, responsive refrigerant metering to maintain optimal superheat levels and maximize system efficiency across a wide range of operating conditions.
Product Overview
Thermostatic expansion valves are the heart of precise refrigerant flow control in split and packaged HVAC systems. The VAL9111 is a direct Trane OEM replacement, ensuring a correct fit and reliable performance in compatible Trane equipment. The external equalizer design senses downstream pressure at the evaporator outlet, allowing the valve to compensate for pressure drop across the coil and maintain consistent superheat — a critical advantage in larger-capacity systems.
