Description
The Johnson Controls VG7441CT+3008E is a factory-assembled, 2-way normally closed control valve paired with a spring return exposed pneumatic actuator — engineered for reliable, precise flow regulation in commercial HVAC hydronic and steam systems.
Valve Overview
The VG7441CT globe-style valve body features a cast bronze construction with brass trim, delivering excellent corrosion resistance and long service life in demanding building automation applications. The equal percentage flow characteristic provides stable, proportional control across the full operating range, making it ideal for variable-flow coil applications where precise temperature control is critical.
