VA9208-GGC-3 Johnson Controls Actuator

Overview

The Johnson Controls VA9208-GGC-3 is a high-performance, direct-mount electric spring return valve actuator designed for precise proportional control of ball valves in commercial HVAC and building automation systems. Upon a loss of power, the integrated mechanical spring return system automatically drives the valve back to its fail-safe position, ensuring process safety and system protection.

Features

• Microprocessor-controlled brushless DC motor provides constant runtime independent of torque.
• Electronic stall detection protects the motor from overload across the entire rotation range without mechanical end switches.
• Two integrated, line-voltage-capable auxiliary SPDT switches for end-stop positioning or safety signaling.
• Manual override crank permits temporary manual positioning and locking of the actuator hub.
• Double-insulated construction eliminates the need for an electrical ground connection.
• Pre-wired 48-inch appliance cable with an integral 3/8-inch flexible metal conduit connector simplifies field installation.
