Siemens SKD62U Flowrite Electro-Hydraulic Actuator
The Siemens SKD62U is a spring-return electro-hydraulic valve actuator that develops 1000 N of positioning force across a 20 mm stroke. Its fail-safe spring return drives the valve to a defined position within 15 seconds during power loss.
Description
- Fail-Safe Spring Return: Drives valve safe in 15 seconds.
- High Positioning Force: Delivers 1000 N for valve seating.
- Overload Protection: Switches off electronically at end positions.
- Flexible Control Input: Accepts 0…10 V, 4…20 mA, 0…1000 Ohm.
- Manual Override: Provides manual control for commissioning.

Description
The Siemens SKD62U is an electro-hydraulic actuator that positions valves with a 20 mm stroke in heating, ventilation, and air-conditioning systems. It develops 1000 N of positioning force and accepts proportional control signals to modulate flow, with a fail-safe spring return for defined valve positioning on power loss.
A die-cast aluminium housing and yoke enclose the unit, which carries an IP54 rating and operates on 24 Vac. It accepts 0...10 V, 4...20 mA, or 0...1000 Ohm positioning signals and includes manual control. Opening takes 30 seconds, and closing takes 15 seconds. One auxiliary switch is optional.
