It features electronic overload protection across the full rotation range to protect internal components during operation. The actuator supports both voltage and current control signals, allowing flexible integration with modern building automation systems. Its terminal block wiring and pluggable position indicator simplify installation, commissioning, and servicing. Key Features Modulating Control Operation: Supports precise 2–10 V proportional control with optional 4–20 mA configuration for stable valve positioning. Non Spring Return Design: Maintains commanded valve position during power loss where fail-safe return is not required. Electronic Overload Protection: Safeguards actuator mechanics throughout the full 0–90° rotation range. Terminal Block Wiring: Enables clean, secure electrical connections in control panels and enclosures. Adjustable Rotation Angle: Mechanical end stops allow fine tuning of valve travel to match application requirements. Manual Override Capability: External push button permits local valve positioning during setup or maintenance. Plenum Rated Construction: UL 2043 compliant design supports installation in air-handling spaces. The ARB24-SR-T delivers the reliability and precision required for proportional valve control in commercial HVAC hydronic systems.
