Johnson Controls VG1845DNH938GGC 1-1/4" 3-Way Ball Valve 11.7 Cv 24V Proportional

The Johnson Controls VG1845DNH938GGC is a 1-1/4" three-way stainless steel trim ball valve assembly with a 24V proportional spring-return electric actuator. It is used to regulate hot or chilled water flow in HVAC systems in response to a controller signal. It is also sold as a 1-1/4" 3-way control valve with actuator or a VG1000 series ball valve assembly.

Key Features:

• Size: 1-1/4" NPT three-way ball valve body from the VG1000 series
• Flow Coefficient: 11.7 Cv
• Actuator: VA9208-GGC-3 24V proportional spring-return electric actuator
• Control: Proportional modulation, with spring return to the normally open position (Port A open, spring return counterclockwise)
• Trim: Stainless steel
• Supply voltage: 24 VAC nominal
• Pressure rating: 200 psig
• Fluid temperature: -22 to 212°F (-30 to 100°C) for standard assemblies
• Service life: Rated for a minimum of 200,000 full cycles
• Compatible media: Water, glycol solutions, and low-pressure steam

The spring-return actuator drives the valve to its fail-safe position if power is lost, which protects coils and equipment. The VA9208 actuator accepts 0(2) to 10 VDC control signals and provides a position feedback signal. This assembly suits mixing or diverting applications in heating and chilled-water loops. Johnson Controls lists the VG1845DNH938GGC as the proportional replacement for the discontinued VG1845DNH938AGC.
