Johnson Controls VG7842ET+71CHGC 1/2" 3-Way Mixing Globe Valve 1.8 Cv with VA7810-HGC-2 Proportional Electric Actuator

The Johnson Controls VG7842ET+71CHGC is a factory-assembled, 1/2-inch NPT three-way mixing globe valve paired with the VA7810-HGC-2 non-spring-return proportional electric actuator. Part of the VG7000 Series, this valve assembly is engineered to regulate the flow of hot water, chilled water, and steam in commercial HVAC systems, delivering precise and reliable fluid control in response to a building automation controller.

Key Features:

• Three-way mixing globe valve with 1/2" NPT end connections and a 1.8 Cv flow coefficient
• Brass trim construction for durability and corrosion resistance across a wide range of HVAC fluids
• Three-way linear flow response for accurate blending of hot and cold fluid streams
• VA7810-HGC-2 proportional electric actuator — non-spring-return type with selectable control modes (On/Off, Floating, or Proportional)
• Two built-in auxiliary switches for end-of-travel position feedback or interlock signals
• Field-selectable stroke speed with factory default set to slowest speed for stable control
• Maximum recommended pressure drop of 35 psid for water; rated for up to 38 psig saturated steam
• Compatible with hot water, chilled water, and 50/50 glycol solutions
• Standard bonnet and stem design enables easy field actuator retrofit and interchangeability
• Factory-assembled and tested for tight shutoff, ensuring energy conservation and occupant comfort

The VG7842ET+71CHGC is ideal for mixing or diverting applications in hydronic HVAC systems where proportional control with auxiliary switch feedback is required. The standardized VG7000 valve body platform supports a broad range of actuator options, making it easy to upgrade or reconfigure in the field.
