The VA9104 Series Actuators are direct-mount, non-spring return electric valve actuators that operate on AC 24 V or 100 to 240 VAC power. Use these synchronous motors or stepper motors (for line voltage models) driven actuators to provide accurate positioning on Johnson Controls® VG1000 Series DN15, DN20, and DN25 (1/2, 3/4, and 1 in.) ball valves in HVAC applications. The VA9104 Series Electric Non-Spring Return Actuators provide a running torque of 35 lbin (4 Nm). The nominal travel time is 60 seconds at 60 Hz for 90° of rotation.
