Johnson Controls VA-4233-GGC-2 Electric Valve Actuator with Spring Return and Proportional Control

The Johnson Controls VA-4233-GGC-2 is a professional-grade electric valve actuator designed for precise control of HVAC dampers and valves in commercial and industrial applications. This actuator features automatic spring return functionality for fail-safe operation and proportional control for accurate modulation.

Key Features:

• 24 VAC/VDC power supply for versatile installation options
• Proportional control with 0-10 VDC or 4-20 mA input signal for precise modulation
• Automatic spring return to fail-safe position on power loss
• Two auxiliary SPDT switches for status indication and control integration
• 75 lbf (334 N) running torque for reliable valve operation
• 1/2 inch (13 mm) stroke length for compact valve applications
• Durable construction suitable for demanding HVAC environments
• Direct mounting to valve stems with included adapters

This actuator is ideal for controlling zone dampers, mixing valves, and other HVAC control applications where proportional modulation and fail-safe spring return are required. The dual auxiliary switches enable system integration for status monitoring, alarm signaling, or interlock control. The VA-4233 Series is designed for long-term reliability in building automation systems.
