Siemens SKP25.003E2 Gas Valve Actuator 230V Pressure Regulating Gov...
The Siemens SKP25.003E2 is an electro-hydraulic actuator used on industrial and commercial combustion systems where reliable gas valve operation and rapid fail-safe closure are required.
SKP25 actuators are safety-critical components. If an actuator fails, the valve may not complete its stroke correctly, often leading to burner lockout or shutdown. This unit is supplied for direct like-for-like replacement where the SKP25.003E2 is specified.
Note: Always match the full Siemens part number and electrical specification shown on the actuator rating plate.
SKP25: Together with a compatible Siemens valve body, the actuator combines safety shut-off with outlet pressure regulation (constant pressure governor), depending on configuration.
Notes: Pressure governor up to 22 mbar
Mains voltage: 230V
Stages: 1-stage
Switch configuration: WITHOUT end switch
Degree of protection: IP54
Weight: 1.6 kg
Opening time for full stroke: 6 to 10 s (depends on valve size)
Opening speed: approx. 2 mm/s
When the actuator is energised, an internal pump transfers hydraulic fluid within the actuator to build pressure in the stroke chamber. This drives the piston to open the gas valve against the return spring.
When power is removed, the pump stops and the internal relief path allows the return spring to drive the piston back, closing the valve quickly to a safe position.
This actuator should be replaced like-for-like. Voltage, switch configuration, and functional type must match the original unit. If you are unsure whether SKP25.003E2 is correct for your valve, our technical team can confirm compatibility before ordering.
You can send a photo of the existing actuator rating plate or valve assembly to ensure correct selection.
Manufacturer technical documentation and installation instructions should be followed during installation and commissioning.
