Johnson Controls VG7842GS+8020G 1/2" Mixing Valve 24V 3-Wire Floating Actuator

The Johnson Controls VG7842GS+8020G is a modulating mixing valve assembly combining a 1/2" brass valve body with an electric actuator for HVAC heating and cooling applications. This complete valve package provides precise control of water flow in hydronic systems including radiant heating, fan coil units, and hot water mixing stations.

Key Specifications:

• Valve body: 1/2" NPT threaded connections with brass construction
• Flow coefficient (Cv): 4.6 for accurate flow characterization
• Actuator: 24V AC/DC 3-wire floating control with spring return
• Control type: Floating point control for modulating applications
• Application: Mixing service for temperature control in hydronic systems
• Direct coupled actuator with integral mounting bracket

This valve assembly is designed for professional installation in commercial and industrial HVAC systems where precise temperature control is required. The 3-wire floating control allows for proportional control when connected to compatible thermostats or building automation systems. The 4.6 Cv rating makes it suitable for applications requiring moderate flow rates in small to medium-sized zones.
