Johnson Controls VG7243CT+423GGC Globe Valve Assembly 1/2 in. NPT 0.73 Cv 24V Proportional Spring-Return with Auxiliary Switch

The Johnson Controls VG7243CT+423GGC is a VG7000 Series stainless steel trim globe valve assembly paired with a VA-4233 Series spring-return electric actuator. Designed for precise flow control in commercial HVAC hydronic systems, this two-way, normally open valve assembly provides reliable regulation of hot water, chilled water, and low-pressure steam applications.

Key Features:

• Valve Body: Two-way, push-down-to-close globe valve with 1/2 in. NPT threaded end connections
• Flow Coefficient: 0.73 Cv with equal percentage flow characteristic
• Actuator Type: VA-4233 Series spring-return electric actuator — stem up on power loss (fail-safe open)
• Control Signal: Proportional (modulating) control for variable flow regulation
• Auxiliary Switch: Integrated auxiliary switch for end-of-travel feedback or interlock applications
• Voltage: 20–30 VAC, 50/60 Hz, 12 VA (nominal 24 VAC)
• Closeoff Force: 61 lb force for tight shutoff
• Close-off Pressure: 230 psig
• Static Pressure Rating: ANSI Class 250 (meets ANSI B16.15 requirements)
• Fluid Temperature Range: 35°F to 250°F (2°C to 121°C); compatible with up to 15 psig saturated steam
• Actuator Operating Range: -20°F to 150°F (-29°C to 66°C)
• Packing: Spring-loaded PTFE and elastomer V-rings for reliable sealing
• Assembly: Factory or field assembly available
• Valve Trim: Stainless steel stem and seat for corrosion resistance

This valve assembly is ideal for HVAC air handling units, fan coil units, and hydronic heating and cooling systems requiring modulating control with auxiliary switch feedback. The spring-return actuator ensures the valve returns to the open (fail-safe) position upon loss of power, providing system protection. Compatible with hot water, chilled water, and 50/50 glycol solutions.
