Johnson Controls VG1845DNH928GGA 1-1/4" 3-Way Ball Valve, 11.7 Cv, 24V Proportional Spring Return

The Johnson Controls VG1845DNH928GGA is a 1-1/4" three-way NPT ball valve assembly for HVAC hot water and chilled water control. It comes with a 24V proportional spring return electric actuator. It is part of the VG1000 Series and is also called a 3-way mixing/diverting ball valve with actuator or a modulating valve actuator assembly.

Key Features:

• 1-1/4" NPT three-way body pattern with a flow coefficient of 11.7 Cv
• Forged brass body with a stainless steel ball and stem
• Characterized insert for equal percentage flow control
• 24V proportional actuator that responds to 0-10 VDC or 2-10 VDC control signals
• Spring return fail-safe operation, so the valve returns to its default position when power is lost
• Suited to hot or chilled water, glycol solutions under 50%, and low-pressure steam (stainless trim models, under 15 psi)
• Series rated for 200 psid close-off pressure and a 580 psig body pressure rating
• Series life expectancy of at least 200,000 full cycles

The actuator is a direct-mount unit that comes mounted to the valve. It gives accurate positioning in HVAC systems controlled by an electronic controller or positioner. This makes the assembly a good fit for mixing and diverting applications such as coil control and heating or cooling loops.
