Johnson Controls VG1845BN+923GGA 3/4" 3-Way Ball Valve with Proportional Spring Return Actuator

The Johnson Controls VG1845BN+923GGA is a factory-assembled combination of a 3/4 in. NPT three-way forged brass ball valve with stainless steel trim and a VA9203-GGA-2Z proportional spring return electric actuator. Designed for precise flow regulation in commercial and industrial HVAC systems, this valve-actuator assembly delivers reliable on-demand control of heating and cooling media.

The VG1845BN valve is part of the VG1000 Series and features a characterized insert for equal percentage flow control, providing Cv ratings comparable to traditional globe valves. The three-way configuration allows for mixing or diverting flow, while the stainless steel trim enables compatibility with a broad range of system fluids.

Key Features:

• 3/4 in. female NPT end connections
• Three-way ball valve configuration (mixing/diverting)
• Flow coefficient (Cv): 11.7
• Closeoff pressure rating: 200 psi
• Stainless steel trim construction
• Equal percentage characterized flow control insert
• Spring return fail-safe action: Port A open (normally open), spring return counterclockwise
• Compatible with chilled water, hot water, up to 50% glycol solutions, and low-pressure steam (15 psig with thermal spacer)
• Maximum working water pressure: 580 psi
• Maximum water temperature: 284°F (140°C)

The factory-mounted VA9203-GGA-2Z actuator operates on 24V AC/DC power and accepts a 0–10V DC proportional control signal for precise positioning. It is a bidirectional spring return actuator providing accurate valve positioning across the full stroke range. The actuator includes a plenum-rated cable, making it suitable for installation in environmental air-handling spaces per NFPA 70 Section 300.22(C).

Actuator Specifications:

• Supply voltage: 24V AC/DC (85–264V AC universal input)
• Control signal: DC 0–10V proportional
• Spring return fail-safe operation
• Plenum-rated cable (VA9203-GGA-2Z)
• Compatible with VG1000 Series 1/2, 3/4, and 1 in. ball valves

This pre-assembled unit simplifies installation and ensures compatibility between valve and actuator. It is engineered for use in heating, ventilating, and air conditioning (HVAC) applications where modulating control and dependable spring return failsafe operation are required.
