The Siemens modulating control valve with a magnetic actuator it is designed for use in chilled and low-temperature hot water systems. With its fast positioning time, high-resolution stroke, and high rangeability, this valve enables precise control of fluid flow. The control valve has an equal-percentage or linear valve characteristic, selectable by the user, and operates on AC/DC 24V power supply. It features a fail-safe feature that ensures the valve closes when de-energized, providing additional safety. This valve is low friction, robust, and requires no maintenance, making it a reliable choice for various applications. Equal-percentage or linear valve characteristic for user-selected control Operating voltage AC/DC 24V for versatile power supply options Switch-selectable control signal DC 0/2 to 10V or DC 4 to 20mA for flexibility Indication of operating state, position feedback, and manual control for easy monitoring Wear-free inductive stroke measurement for reliability and durability Fail-safe feature ensures valve closure when de-energized for added safety Low friction, robust design that requires no maintenance for easy operation
