The Siemens SKD62U is a highly functional electro-hydraulic valve actuator suited for demanding environments. With a voltage rating of 24 Vac and a tolerance of -20% to +30%, this actuator operates efficiently within typical electrical systems. This actuator is part of the SKD6xU series, designed to meet various operational needs.

The actuator functionally incorporates a spring return mechanism, which ensures fail-safe operation during emergencies or power losses. It operates across a wide ambient temperature range of -15 to 50 °C and maintains functionality with a humidity range from 5% to 95% RH. The maximum permissible temperature of the medium handled can reach up to 150 °C, accommodating a variety of processes.

Positioning force ratings are impressive, providing 1000 N for normally closed (NC) operations through the upper port and up to 1150 N for normally open (NO) bypass configurations. Power consumption does not exceed 17 VA or 12 W, making it efficient for continuous use. The nominal stroke of this actuator measures 20 mm, and it can complete its closing action in just 15 seconds. Additionally, this model carries an IP54 rating, which signifies its robust construction against dust and water exposure.
