Why Choose the VG1845AD
The equal percentage flow characteristic of the VG1845AD provides excellent controllability at low flow rates while maintaining precise modulation at higher loads — making it ideal for variable-flow hydronic systems. The forged brass body withstands the pressures and temperatures typical of commercial HVAC applications, and the stainless steel trim resists the corrosive effects of treated water and glycol solutions. As part of the Johnson Controls valve family, the VG1845AD is designed to integrate seamlessly with Johnson Controls actuators for a complete, reliable control solution.
