Johnson Controls VG1845BNH923BGA 3/4 in. Three-Way Ball Valve with Spring-Return Actuator 11.7 Cv 24V

The Johnson Controls VG1845BNH923BGA is a factory-assembled, three-way ball valve from the VG1000 Series, paired with a spring-return electric actuator. Designed for commercial and industrial HVAC applications, this combination provides reliable on/off flow control for chilled water, hot water, and 50% glycol systems. The stainless steel trim construction and NPT end connections make it well-suited for demanding building automation environments.

Key Features:

• Valve Size: 3/4 in. (DN20) with NPT threaded end connections
• Flow Configuration: Three-way body pattern for mixing or diverting applications
• Flow Coefficient (Cv): 11.7 — equal percentage characterized flow control
• Actuator Type: Spring-return electric actuator — fail-safe operation on loss of power
• Control Signal: Two-position (On/Off) — 24V AC/DC supply
• Trim Material: Stainless steel for enhanced corrosion resistance
• Media Compatibility: Chilled water, hot water, and 50% glycol solutions
• Direct-coupled actuator: Factory-mounted for reduced field installation time
• Part of the VG1000 Series — a comprehensive family of ball valves with Cv ratings ranging from 1.2 to 73.7

The VG1845BNH923BGA ships as a pre-assembled valve and actuator unit, eliminating the need for field linkage assembly and reducing installation complexity. The spring-return mechanism ensures the valve returns to a defined fail-safe position in the event of a power interruption, making it an ideal choice for critical HVAC control loops in building automation systems (BAS).
