The VA9104 Series actuators are direct-mount, non-spring-return electric valve actuators that operate on AC 24 V power. Use these synchronous motor-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 (72 seconds at 50 Hz) for 90° of rotation.
