Product Overview
The Johnson Controls VG1205GT-C / VA9320-HGA-3 is a factory-matched motorized globe valve assembly engineered for precise modulating and two-position control of hot water, chilled water, and low-pressure steam in commercial and industrial HVAC and process systems. The VG1205GT-C valve body is a two-way, normally open globe valve with a bronze construction and a replaceable composition disc, providing tight shutoff and characterized flow for stable temperature and pressure regulation. It is driven by the VA9320-HGA-3 electric actuator, a non-spring-return, proportional (0–10 VDC / 4–20 mA) motorized actuator featuring a synchronous motor, magnetic clutch, and manual override for commissioning and fail-safe positioning. Together, the assembly delivers accurate valve positioning, low hysteresis, and long service life in hydronic balancing, coil control, and process fluid regulation applications.
