Johnson Controls VG7842GT+3008E 1/2" Brass Globe Valve with Pneumatic Actuator

The Johnson Controls VG7842GT+3008E is a commercial-grade three-way mixing valve assembly designed for precise temperature control in HVAC hydronic systems. This compact 1/2-inch valve combines the Series VG7000 Model VG7842GT brass trim globe valve body with the V-3000-8012 exposed pneumatic actuator for reliable modulating control.

Key Specifications:

• Valve Size: 1/2 inch NPT threaded connections
• Configuration: Three-way mixing valve for diverting or mixing service
• Flow Coefficient (Cv): 4.6 - suitable for small to medium capacity systems
• Body Material: Durable brass construction with brass trim for corrosion resistance
• Actuator Type: V-3000-8012 exposed pneumatic actuator
• Spring Range: 9-13 psig for direct acting control
• Action: Spring return design for fail-safe operation

This valve assembly is ideal for hot water heating systems, chilled water applications, and other hydronic systems requiring accurate proportional control. The pneumatic actuator provides smooth modulating control in response to pneumatic control signals from building automation systems or standalone controllers. The brass construction ensures long-term reliability in commercial and industrial installations.

The three-way mixing configuration allows for blending of hot and cold water streams or diverting flow between two circuits, making it versatile for applications such as radiant heating control, fan coil units, unit heaters, and heat exchanger bypass control.
