Features:
- Three-position 230 V AC control drives opening and closing separately.
- The hydraulic mechanism produces 2800 N over a 40 mm stroke.
- This actuator version has no spring-return movement.
Siemens SKC32.60 converts two directional control signals into hydraulic valve-stem movement.
The internal pump and cylinder move the stem, while end switches stop the drive at the travel limits.
Manual control and mounting clearances support commissioning without changing the actuator’s three-position operating principle.
The Siemens SKC32.60 code identifies the 230 V AC three-position actuator without spring return; spring-return SKC variants use different codes.

Three-Position Command Logic
- Opening: One 230 V AC command drives the actuator toward open.
- Closing: The opposite command drives the actuator toward closed.
- Hold: Removing both commands stops powered travel at the present position.
- Timing: A complete opening or closing stroke requires the documented 120 s.
Hydraulic Positioning Mechanism
- Pump: The motor-driven pump raises hydraulic pressure for stem travel.
- Cylinder: Hydraulic pressure converts motor rotation into linear motion.
- Force: The actuator delivers the documented 2800 N positioning force.
- Return: Reverse travel uses the opposite command rather than a spring.
Valve and Mechanical Installation
- Stroke: The actuator is designed for a 40 mm valve stroke.
- Clearance: Space above and beside the actuator must allow service access.
- Coupling: The actuator stem and valve stem must align before tightening.
- Orientation: The approved mounting positions preserve enclosure protection and hydraulic operation.
Temperature and Enclosure Conditions
- Enclosure: The housing provides IP54 protection in the stated installation.
- Storage: Storage is specified from -15 to +55 °C.
- Humidity: Storage humidity extends from 5% to 95% RH without condensation.
- Medium: Valve-medium limits depend on the valve combination and stem-heater condition.
