It supports both on/off and floating control modes, allowing flexible integration with a wide range of building automation controllers. The actuator provides high torque output to handle larger valve sizes while maintaining smooth and controlled rotation. Its compact design, integrated cable, and selectable direction of motion simplify installation and commissioning in HVAC control applications. Key Features High torque capability: Delivers 180 in-lb of torque to reliably actuate ball valves ranging from 1-1/4 inch to 3 inches in diameter. Non-spring return operation: Designed for applications where fail-safe positioning is not required and controlled motor-driven operation is sufficient. Flexible control modes: Supports both on/off and floating control to accommodate different control strategies. Selectable rotation direction: Motor direction can be configured via internal switch to match valve installation requirements. Adjustable rotation angle: Mechanical stop allows precise limitation of rotation travel for accurate valve positioning. Integrated manual override: External push-button enables manual operation during setup, testing, or maintenance. Electronic overload protection: Protects internal components throughout the full rotation range to enhance reliability and service life. The ARB24-3 delivers the reliability and precision required for dependable electric actuation of large ball valves in commercial HVAC control systems.
