Johnson Controls VG7842NT+3008B 3-Way Globe Valve 1" NPT with Pneumatic Actuator

The Johnson Controls VG7842NT+3008B is a complete valve and actuator assembly designed for precise control of heating, cooling, and process fluids in commercial HVAC applications. This unit combines the Series VG7000 Model VG7842NT brass trim globe valve with the Model V-3000-8012 exposed pneumatic actuator for reliable modulating control.

Key Specifications:

• 3-way valve configuration for mixing or diverting service
• 1 inch NPT threaded connections
• Flow coefficient (Cv) of 11.6 for accurate flow calculation
• Brass trim construction for durability and corrosion resistance
• V-3000 series exposed pneumatic actuator
• 3-6 psig spring range for precise modulating control
• Direct mount actuator-to-valve assembly

Applications:

Ideal for use in commercial heating and cooling systems, fan coil units, heat exchangers, and other HVAC applications requiring accurate proportional control of water, glycol solutions, or other compatible fluids. The 3-way design allows for either mixing two inlet streams or diverting one inlet to two outlets.

The pneumatic actuator responds to control signals from building automation systems to modulate valve position, providing energy-efficient temperature control and system balancing. The 3-6 psig spring range is compatible with standard pneumatic control systems.
