Kromschroder Actuator IC50-60W30E 74215230

The Kromschroder IC50-60W30E actuator (SKU 74215230) is a rotary actuator designed for precise control of butterfly valves, specifically the DKR type, for modulating air and flue gas flow. It operates on a three-point step signal with a supply voltage of 230 V AC and a frequency range of 50/60 Hz. The actuator provides a torque of 30 Nm and has a duty cycle of 100%, allowing continuous operation. It features a holding torque equal to the torque, which is adjustable. The device has a weight of 2500 g, protection class IP, safety class 1, and is designed for ambient temperatures without condensation. It complies with directives 2014/35/EU and 2014/30/EU, and standard EN 60730:2011, with manufacturing under DIN EN ISO 9001 quality system.

When selecting an actuator of this type, ensure the supply voltage, frequency, and control signal (three-point step) match the existing system. The torque and running time must be compatible with the valve's requirements. Check the shaft dimensions and mounting arrangement to fit the valve. The actuator should be installed with proper cable glands and wiring, ensuring no condensation forms in the operating environment. Verify that the holding torque is set appropriately for the application.

Common failures include loss of torque or inability to hold position, often due to worn gears or electrical issues. The actuator may fail to respond to control signals, or it may move erratically. Check for loose connections, damaged cables, or moisture ingress. If the actuator stalls or makes unusual noises, inspect the mechanical linkage and valve for obstructions.
