Siemens SKB / SKC Electrohydraulic Valve Actuator 2800 N
Siemens SKB / SKC Electrohydraulic Valve Actuator 2800 N
The Siemens SKB / SKC series are electrohydraulic actuators that drive large flanged valves and high differential pressure applications with 2800 N of positioning force. The SKB32.50 offers a 20 mm stroke and the SKC models a 40 mm stroke; they can be used with valves for medium temperatures of −25…220 °C.
The SKB32.50 and SKC32.60 operate at AC 230 V with 3-position control, while the SKC60 has an AC 24 V supply and modulating control with a DC 0…10 V / 4…20 mA signal. Compatible valves are listed below.

This list is verified compatibility information based on Siemens product matching data; it is not a list of similar-product suggestions. You can make the final selection with our engineering team based on your project conditions (differential pressure, stroke, control signal).
Selection and installation notes
- The actuator's actuating force and stroke must match the close-off pressure and stroke of the valve it is fitted to.
- The supply voltage and control signal (3-position, DC 0…10 V or on/off) must match the controller output.
- Refer to the datasheet for mounting position and ambient temperature limits.
