Trane VAL11170 Expansion Valve L99H008 visible carbon build-up or "pitting"The Trane VAL11170 is a high precision electric expansion valve (EEV) engineered for 4 ton HVAC systems requiring meticulous refrigerant metering. Designed as an OEM Trane replacement part, this 1. 8 mm nominal size valve utilizes an electronic actuator to modulate flow based on real time temperature and pressure feedback. This level of control is essential for maintaining optimal superheat levels and maximizing the efficiency of R 410A systems. Rated
