It accepts both 0–10 VDC and 4–20 mA control signals, enabling proportional operation across a wide range of applications. With a 20 mm stroke and 800 N of force, it is designed for Flowrite 599 Series 2-way/3-way valves and Siemens pressure-independent control valves. Built with overload protection, stroke feedback, and manual override, the actuator ensures reliability, ease of setup, and minimal maintenance in demanding environments. Key Features: Dual Control Signal Support: Accepts both 0–10 VDC and 4–20 mA proportional inputs for flexible system integration. Strong Positioning Force: Delivers 800 N of thrust to operate Flowrite and Siemens PICV valves effectively. Fast Positioning: 30-second stroke movement ensures responsive valve control in HVAC applications. Wide Compatibility: Designed for Siemens Flowrite 599 2-way/3-way and flanged PICV valves with 20 mm stroke. Operating Voltage: Runs on 24 VAC or VDC, ensuring standard power compatibility in control systems. Position Feedback: Provides visual and electronic indication of stroke position for monitoring and diagnostics. Manual Override: Allows operators to manually adjust positioning with automatic recalibration afterward. Protection Features: Includes overload and stall protection for safe and durable operation. Optional Accessories: Supports auxiliary switches, stem heater, and function modules to expand functionality. Rugged Design: Built for continuous use with permissible operating media temperatures from -25 °C to +130 °C. The SAX61.03U delivers the reliability and precision required for accurate HVAC valve control, combining strong actuation force, flexible input options, and long-term durability.
