Johnson Controls VG1845BN+943BGA 3/4" 3-Way Ball Valve Assembly with 24V Spring Return Actuator, Cv 11.7, Normally Closed

The Johnson Controls VG1845BN+943BGA is a factory-assembled combination of a 3/4-inch, three-way forged brass ball valve and a VA9203-BGA series 24V two-position spring return electric actuator. Designed for use in commercial and industrial HVAC systems, this pre-matched assembly provides reliable on/off flow control of hot water, chilled water, or 50% glycol solutions with a normally closed (NC) fail-safe configuration.

The VG1845BN valve body features a stainless steel ball and stem, a forged brass body rated to 580 psig static pressure, and a characterized insert for equal percentage flow control with a Cv of 11.7. The 3/4-inch female NPT threaded connections make installation straightforward in standard piping configurations.

Key Features:

• 3/4" Three-Way Configuration — Female NPT (FNPT) threaded connections for diverting or mixing applications
• Cv 11.7 — Characterized flow insert delivers equal percentage flow control across the full range
• Stainless Steel Ball and Stem — Provides durability across chilled water, hot water, and 50% glycol applications
• Forged Brass Body — Rated to 580 psig static working pressure; 200 psig closeoff pressure
• Graphite-Reinforced PTFE Seats — 15% graphite-reinforced ball seals for improved wear resistance and long service life
• 24V AC/DC Spring Return Actuator — Two-position (on/off) control; spring return ensures normally closed fail-safe operation on power loss
• Direct-Coupled Actuator — Factory-mounted VA9203-BGA actuator eliminates field linkage assembly and reduces installation time
• Maintenance-Free Design — Tested to perform in excess of 200,000 full stroke cycles
• 500:1 Rangeability — Accurate flow control across all load conditions

The VG1845BN+943BGA is part of the Johnson Controls VG1000 Series and is compatible with building automation systems (BAS) requiring simple two-position control signals. The assembly ships pre-configured and ready for installation, making it ideal for terminal unit, fan coil, and air handling unit coil applications in HVAC environments.
