Johnson Controls VG7441PT+423GGC 2-Way Globe Valve Assembly with Proportional Electric Actuator and Dual Auxiliary Switches

The Johnson Controls VG7441PT+423GGC is a factory-coupled valve and actuator assembly combining a VG7000 Series brass trim bronze globe valve with a VA-4233-GGC-2 spring-return electric actuator. Designed for precise flow control in commercial HVAC systems, this assembly is ready to install with no additional linkages required.

The VG7441PT valve is a two-way, normally closed (push-down-to-close) globe valve with a 1-1/4 in. NPT end connection and an 18.5 Cv flow coefficient. It is suitable for use with hot water, chilled water, or low-pressure saturated steam in a fluid temperature range of 35 to 284°F (2 to 140°C) with a 38 psig close-off pressure rating.

The VA-4233-GGC-2 actuator (denoted by the +423GGC suffix) provides 0 to 10 VDC proportional control with two integral auxiliary switches for end-stop position indication or supplemental switching functions. It uses a stepper motor with automatic AUTO stroke calibration, eliminating manual adjustment at installation. In the event of a power failure, an integrated spring automatically returns the valve stem to the full up (closed) position.

Key Features:

• Valve Size: 1-1/4 in. NPT end connections

• Valve Action: Two-way, normally closed (push-down-to-close)
• Close-Off Pressure: 38 psig
• Control Signal: 0 to 10 VDC proportional (switch selectable: 0–10 VDC, 2–10 VDC, 6–9 VDC, 0–20 mA, or 4–20 mA)
• Actuator Power Supply: 24 VAC/VDC, 50/60 Hz
• Auxiliary Switches: Two integral SPDT auxiliary switches with adjustable switch points
• Spring Return: Automatic spring return to full stem-up (closed) position on power loss
• Force Output: Minimum 61 lb-in (271 N)
• Stroke: Maximum 29/32 in. (23 mm); nominal travel time 76 seconds
• Electrical Connection: 48 in. (122 cm) cable with 20 AWG wire leads; auxiliary switch cable 48 in. with 18 AWG leads
• Certifications: UL 873 Listed; CSA C22.2 No. 139 Certified
• Valve Trim: Brass trim, bronze body

This assembly is ideal for building automation systems (BAS) requiring accurate fluid management in heating and cooling applications. The factory-coupled design and AUTO stroke calibration reduce installation time and cost, while the dual auxiliary switches provide added system monitoring and control flexibility.
