Trane VAL11996 7/8 x 5/8 in. Electronic Expansion Valve

Description

The Trane VAL11996 is an OEM electronic expansion valve (EXV) designed for precise refrigerant flow control in Trane HVAC systems. Featuring 7/8″ inlet and 5/8″ outlet connections, this electronically controlled valve replaces traditional thermostatic expansion valves (TXVs) with a stepper-motor-driven design that responds dynamically to system demand — delivering tighter superheat control, improved efficiency, and extended equipment life.

Key Features

• OEM Trane replacement electronic expansion valve (EXV)
• 7/8″ inlet x 5/8″ outlet connection sizes
• Stepper motor-driven design for precise, stepwise refrigerant metering
• Enables tighter superheat control compared to traditional TXV designs
• Improves system efficiency and reduces energy consumption under variable load conditions
• Compatible with Trane control boards and EXV driver modules
• Engineered for reliable, long-service-life operation in commercial and residential Trane equipment

Benefits of Electronic Expansion Valves

Unlike fixed or thermostatic expansion valves, electronic expansion valves continuously modulate refrigerant flow based on real-time system feedback from the unit’s controller. This results in optimized evaporator performance across a wide range of operating conditions, reduced compressor cycling, and improved overall system COP (coefficient of performance). The VAL11996 is the direct OEM replacement, ensuring full compatibility and performance restoration in applicable Trane equipment.

Application

• Trane commercial and residential split systems, heat pumps, and packaged units requiring EXV replacement
• Ideal for service technicians performing precision refrigerant-side repairs on Trane equipment
