The Johnson Controls VA-7452-90011 electric valve actuator provides proportional control HVAC applications. The compact design of this actuator makes it ideal for installations in confined locations, such as fan coil applications. The Johnson Controls VA-7452-90011 is designed for easy mounting in the field, or may be ordered factory coupled to Johnson Controls® VG4000 or VG5000 Series Zone Valves. Refer to the VA-7450 Series Electric Valve Actuators Product Bulletin (LIT-977324) for important product application information.
Features
The Johnson Controls VA-7452-90011 includes auto-commissioning, which simplifies installation, since the actuators require no adjustments in the field. The auto-shutoff actuator motor extends actuator life by reducing drive time and excessive motor wear, while the durable, heat-stabilized, plastic resin enclosure allows the actuator to be used in applications with fluid temperatures up to 203°F (95°C). The VA-7452-90011 can be mounted after the valve body is piped, simplifying installation and providing application flexibility. This actuator may even be rotated after it is mounted on the valve body, simplifying installation by allowing the actuator wiring entry to be located in any direction. LED provides direct, visual indication of the actuator operating status.
