Johnson Controls VG7842ET+3008D 1/2" Brass Globe Valve with Pneumatic Actuator

The Johnson Controls VG7842ET+3008D is a high-performance control valve assembly combining a Series VG7000 brass trim globe valve with an exposed pneumatic actuator. This 1/2-inch three-way mixing valve is designed for precise temperature control in HVAC hydronic systems, featuring a 1.8 Cv flow coefficient for optimal fluid regulation.

Key Features:

• 1/2-inch NPT threaded connections for easy installation
• Three-way mixing valve configuration for temperature blending applications
• 1.8 Cv flow coefficient provides accurate flow control
• Durable brass trim construction for corrosion resistance and long service life
• Model V-3000-8012 exposed pneumatic actuator with 4-8 psig spring range
• Direct-acting spring return actuator for fail-safe operation
• Ideal for chilled water, hot water, and hydronic heating/cooling systems

This valve assembly is commonly used in commercial HVAC applications including fan coil units, unit heaters, terminal units, and hydronic control systems where reliable proportional control is essential. The pneumatic actuator provides smooth modulation in response to control signals from compatible thermostats and controllers.
