The Siemens modulating control valve with a magnetic actuator. It is designed for use in chilled and low-temperature hot water systems or for systems with media containing mineral oils. With a fast positioning time of less than 2 seconds and a high-resolution stroke of 1:1000, this valve offers precise control and high rangeability. It operates on an AC / DC 24 V power supply and has a switch-selected control signal of DC 0/2 to 10 V or DC 4 to 20 mA. The control valve also features wear-free inductive stroke measurement and a fail-safe feature that closes the valve when de-energized. Fast positioning time of less than 2 seconds
