More Information

Overview Manuals Control Hydraulics Mounting Environment

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.
Description
Siemens SKC32.60 is an Acvatix electrohydraulic actuator that moves compatible control-valve stems through a 40 mm stroke with 2800 N positioning force. Its 230 V AC three-position input commands opening or closing, while removal of both commands stops travel at the current position.

Inside SKC32.60, the motor-driven hydraulic pump builds pressure to move the actuator cylinder and valve stem. The return hydraulic path follows the opposite electrical command because this version has no spring-return function.

End-position switches in SKC32.60 remove drive power at the mechanical limits, and the manual control allows the stem position to be changed during commissioning when the permitted procedure is followed. The 120-second travel time applies to both opening and closing movement.

When SKC32.60 is fitted to a valve, the mounting clearance and medium-temperature limits must be checked together. A stem heater is required for the documented sub-zero medium condition, while the IP54 enclosure rating depends on the stated mounting arrangement.

Technical notes
Because SKC32.60 has no spring return, loss of the 230 V AC control supply leaves valve movement without an automatic return stroke; system behavior must be designed accordingly.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Why does SKC32.60 stop between the valve end positions?
Check whether both control signals were removed, then verify the SKC32.60 supply, command wiring, end switches, manual-control position, and valve stem for binding.
Will SKC32.60 return the valve to a safe position after power loss?
No. SKC32.60 has no spring-return function, so the system must not rely on an automatic return stroke when power is lost.
What causes SKC32.60 to run in the wrong direction?
Verify that the opening and closing conductors are connected to the correct SKC32.60 control terminals and that the controller outputs are not reversed.
Why does SKC32.60 reach one limit but not complete the other stroke?
Inspect SKC32.60 coupling alignment, valve travel, mechanical obstruction, mounting clearance, command voltage, and the corresponding end-position switch.
When is a stem heater relevant to SKC32.60 installation?
A stem heater is required when SKC32.60 operates with the documented valve arrangement and medium temperature below 0 °C.
How should manual control be left before SKC32.60 returns to automatic operation?
Return the SKC32.60 manual-control mechanism to its normal operating state and confirm free valve travel before applying electrical commands.
