Johnson Controls VA-6100-HGC Valve Actuator

The Johnson Controls VA-6100-HGC is a high-torque electric valve actuator engineered for precise proportional control in demanding commercial HVACR environments. Operating on 24 Vac power, this unit is specifically designed for N-stem integration on 4-inch to 6-inch valves, delivering an 1115 lb force to manage high differential pressures. The 0 to 10 Vdc or 0 to 20 mA input signal compatibility ensures seamless communication with building automation systems (BAS), allowing for granular modulating valve adjustments that stabilize hydronic flows. This model features two auxiliary switches for status feedback and end-stop verification, reducing troubleshooting time in the field. Built with a robust housing and a brushless DC motor, the VA-6100-HGC maintains consistent torque throughout its stroke, ensuring reliable performance in large-scale air handling units and central plant configurations. For technicians, the manual override and position indicator simplify commissioning and seasonal maintenance workflows.

• High-Force Output: Specifically engineered to handle the mechanical resistance of 4-inch to 6-inch large-bore valves.
• Universal Control Input: Supports both 10V and 20mA signals for maximum field flexibility with various controllers.
• Dual Auxiliary Switches: Factory-installed switches provide reliable remote confirmation of valve position.
• Precision Modulation: Eliminates hunting and short-cycling in high-capacity hydronic loops.
• N-Stem Compatibility: Direct-mount design ensures rigid coupling and accurate stroke calibration.

Can the VA-6100-HGC be field-configured for different input signals?
Yes, the actuator is designed to accept either a 0-10 Vdc or 0-20 mA proportional signal, making it compatible with most standard industrial and commercial DDC systems.

What is the primary application for this specific actuator model?
This technician-grade actuator is primarily utilized for modulating hot water or chilled water flow in large-scale piping systems that utilize Johnson Controls valves with an N-style stem.

Are the auxiliary switches adjustable?
The dual auxiliary switches are integrated to provide fixed position feedback, typically utilized to signal a fully open or fully closed state to the building controller.
