Robust Build: High-grade aluminum housing provides superior resistance to vibration and temperature fluctuations in mechanical rooms

provided the venting and inducer motor are functioning correctly

providing reliable proof of airflow for burners

Integrated Safety: Redundant internal switches ensure the damper is fully open before allowing the gas valve to energize

Trane VAL11170 Expansion Valve 326058-757 Robust Build: High-grade aluminum housingThe 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
