Johnson Controls VG1845BNH923GGA 3/4" Three-Way Ball Valve with Proportional Spring-Return Actuator 11.7 Cv 24V

The Johnson Controls VG1845BNH923GGA is a factory-assembled combination of a 3/4-inch, three-way stainless steel trim NPT ball valve and a proportional spring-return electric actuator, engineered for precise flow control in commercial and industrial HVAC systems. Part of the VG1000 Series, this assembly delivers reliable modulating control for chilled water, hot water, 50% glycol, and low-pressure steam applications.

The VG1845BN valve body features a characterized ball insert for equal percentage flow characteristics, a flow coefficient (Cv) of 11.7, and NPT end connections rated to 200 psi. The three-way configuration allows diverting or mixing service, making it well suited for terminal unit and air handling applications.

The integrated H923GGA (VA9203-GGA series) actuator provides proportional spring-return operation on 24V AC/DC power with a 0–10 VDC control signal. On loss of power, the actuator automatically spring-returns to its fail-safe position. The proportional GGA control version supports input signal range selection and control logic reversal for flexible commissioning.
