The Johnson Controls VA-7482-0312 electric valve actuator. 24 VAC/VDC, proportional,
Input Signal: 0 to 10 VDC, 2 to 10 VDC, 0 to 5 VDC, 5 to 10 VDC, 0 to 20 mA, or 4 to 20 mA
VA-748x Series Electric Valve Actuators provide floating or proportional control in HVAC applications. The compact design of this actuator series makes it ideal for installations in confined locations, such as fan coil applications. The VA-748x Series Actuator is designed for field mounting onto the terminal unit valves made by Johnson Controls and its competitors. Due to the innovative concept of auto stroke detection, the VA-748x actuator can be installed over most of the conventional terminal unit valves in the market and pressure independent control valves with variable strokes.
Features:
- Auto-commissioning simplifies installation, since models require no adjustments in the field
- Auto-shutoff actuator motor extends actuator life by reducing drive time and excessive motor wear
- Durable, heat-stabilized, plastic resin enclosure allows the actuator to be used in applications with fluid temperatures up to 203°F (95°C)
- Actuator can be mounted after the valve body is piped, simplifying installation and providing application flexibility
- Compact design allows for installation in confined locations, such as fan coil applications
- Operating status LED provides direct, visual indication of the actuator operating status
- Actuator can be rotated after it is mounted on the valve body, simplifying installation by allowing the actuator wiring entry to be located in any direction
