Johnson Controls VG7842ST+3008E Mixing Globe Valve with Pneumatic Actuator - 2-Inch 3-Way

The Johnson Controls VG7842ST+3008E is a professional-grade control valve assembly combining a Series VG7000 brass trim globe valve with an exposed pneumatic actuator for precise fluid control in HVAC systems. This 2-inch, 3-way mixing valve features a bronze body construction with brass trim for durability and corrosion resistance in commercial and industrial applications.

Key Specifications:

• Valve Size: 2-inch NPT threaded connections
• Configuration: 3-way mixing valve for blending hot and cold fluids
• Flow Coefficient (Cv): 46.2 for high-capacity applications
• Body Material: Bronze construction with brass trim components
• Actuator: Model V-3000-8012 exposed pneumatic actuator
• Spring Range: 9-13 psig for proportional control
• Action: Direct-acting for fail-safe operation

Features and Benefits:

• Brass trim provides smooth operation and extended service life
• High flow capacity (Cv 46.2) minimizes pressure drop in large systems
• Pneumatic actuation delivers reliable, proportional control without electrical connections
• 3-way mixing design allows for blending of supply streams or diverting applications
• Exposed actuator simplifies installation, maintenance, and troubleshooting
• Spring-return design ensures consistent response across the control range

This valve assembly is ideal for heating and cooling coil applications, heat exchangers, and other HVAC systems requiring precise temperature control through fluid mixing. The pneumatic actuator responds proportionally to control air pressure, making it compatible with standard pneumatic control systems.
