Siemens Actuator SKP15 Series

Siemens SKP15 Series – Electrohydraulic Gas Safety Shutoff Actuators

Siemens SKP15 Series actuators use electrohydraulic technology to operate gas safety shutoff valves in industrial combustion installations. They deliver two-position OPEN/CLOSED control when fitted to compatible Siemens VGx/VRx gas valves.

The SKP15 opens the connected gas valve gradually and closes it rapidly when electrical power is removed. This operating arrangement supports gas safety shutoff in industrial burners, boiler combustion equipment and gas-fired heating installations.

Key Features

• Electrohydraulic actuator for compatible gas valves
• Two-position OPEN/CLOSED safety shutoff control
• Gradual valve opening and fast closure
• Safety shutoff according to EN 161 when combined with suitable approved valves
• Maximum electrical consumption of 10 VA for European versions
• Suitable for gas families I–III, subject to valve compatibility
• Available with or without a factory-adjusted end switch
• Plug-in connection for the electrical supply

How the SKP15 Actuator Works

When energized, an internal hydraulic pump builds oil pressure, moving the piston to open the gas valve progressively. If power is disconnected or interrupted, the closing spring returns the valve to its closed position. The valve closes in less than one second.

Industrial Applications

• Industrial gas burner systems
• Gas-fired boiler combustion installations
• Industrial furnace equipment
• Gas-powered industrial heating systems
• Gas safety shutoff valve assemblies

SKP15 Model Variants

• SKP15.000E1 – AC 120V, without end switch
• SKP15.000E2 – AC 230V, without end switch
• SKP15.001E1 – AC 120V, with end switch
• SKP15.001E2 – AC 230V, with end switch

Important: The SKP15 is intended solely for OPEN/CLOSED safety shutoff and does not regulate gas pressure. Confirm valve compatibility, rated supply voltage and required electrical accessories before installation.
