VA7820-HGA-2

The VA7820-HGA-2 electric valve actuator from Johnson Controls is engineered for diverse applications requiring precise valve management. It features a considerable torque capacity of 180 lb-in, providing strong performance for various types of valves. At a weight of 5.4 lbs, the actuator is lightweight enough for easy handling while delivering substantial operational power.

With a fail-safe design that implements a spring-return stroke (stem up), it ensures that the valve returns to a safe position in the event of power loss. This product operates on an AC voltage input of 24 volts, making it suitable for low-voltage applications.

In terms of control, the actuator accepts a proportional control signal ranging from 0-10 Volts DC, which can be configured as either on/off or floating depending on operational needs. This flexibility allows for adaptability in various control strategies. Stroke length adjustments can be set anywhere from 5/16 inch to 1 inch.

The VA7820-HGA-2 actuator is compatible with VG7000 bronze globe valves, covering sizes from 1/2 inch to 2 inches, ensuring versatility across many valve assemblies. Notably, the actuator does not come with auxiliary switches, simplifying its configuration and usage.

Enclosure ratings are crucial for ensuring the actuator functions properly in varying environments. The VA7820-HGA-2 has a NEMA 2 rating, ensuring protection against limited dust and indirect water, while its IP54 rating further enhances its operability by providing dust ingress protection and resistance to water splashes. It operates effectively in temperatures ranging from -5 to 55 degrees Celsius, making it adaptable to different climate conditions. Lastly, the actuator has a VA rating of 11, indicating its power consumption efficiency during operation.
