Johnson Controls VG7842NT+74CHGA Mixing Globe Valve with Electric Actuator - 1 3-Way

The Johnson Controls VG7842NT+74CHGA is a complete valve assembly combining a 1-inch NPT 3-way mixing globe valve with a VA7840-HGA-2 series spring return electric actuator. This bronze valve with brass trim is designed for hot water, chilled water, or saturated steam applications in HVAC systems, with a fluid temperature range of 35 to 284°F and a flow coefficient (Cv) of 11.6.

Key Features:

• Three-way linear flow response for excellent control
• Spring return actuator with DC 0 to 10V proportional control
• Field configurable for On/Off or Floating Control via DIP switch settings
• 24VAC power supply with spring return stem down failsafe operation
• Direct mount actuator with minimum linear output force of 180 lb
• Cast bronze body with brass trim construction for durability
• Selectable control modes without auxiliary switches

Maximum recommended pressure drop for water is 35 psid for this 1-inch valve size. The assembly is ideal for mixing applications in commercial and industrial HVAC systems where precise flow control and reliable failsafe operation are required.
