Siemens Combustion SKP55.013U1 Actuator
The Siemens Combustion SKP55.013U1 Actuator is a specialized electro-hydraulic solution designed for precise air/gas ratio control in industrial and commercial burner systems. Operating on a 120V power supply, this high-performance component integrates three critical functions—safety shut-off, constant pressure regulation, and differential pressure (dP/dP) ratio maintenance—into a single modular unit. By monitoring differential pressure across restrictions in both gas and air lines, the SKP55.013U1 ensures a constant combustible mixture even when air volume fluctuates. This ratio regulating actuator is primarily utilized with Siemens VG series gas valve bodies, streamlining gas train assemblies by eliminating the need for separate upstream regulators. It features a slow-opening mechanism for controlled ignition and a fast-closing safety response, typically under 0.8 seconds, upon power interruption. The modular design allows for 360-degree rotation, facilitating easier field wiring and installation in tight mechanical spaces. This specific SKP55.013U1 configuration is supplied without auxiliary or Proof of Closure (POC) switches, making it a direct solution for standard burner control applications where simple, reliable stoichiometric tracking is the priority.
Key Benefits- Integrated Functionality: Combines safety shut-off and ratio regulation, reducing the number of fittings and overall gas train footprint.
- Precise Ratio Maintenance: Maintains an accurate air to gas ratio even during air flow disruptions or fluctuations in combustion chamber back pressure.
- Operational Clarity: Features a visible stroke position indicator and a "power on" light for immediate field diagnostics.
- Universal Compatibility: Mounts easily to all Siemens VG valves from 1/2-inch to 6-inch via a standard four-bolt flange.
- Low Power Consumption: Efficient 13.5 VA operation reduces the load on the control circuit.
Is the SKP55.013U1 compatible with preheated combustion air?
Yes, this actuator is an excellent choice for recuperative burners using preheated air, as it compensates for air/gas density changes to maintain the set ratio.
Can I field-install auxiliary switches on this model?
No. The Siemens SKP55.013U1 is the base model without switches. If you require Proof of Closure or auxiliary switches, you must order the specific model (e.g., SKP55.011U1 or SKP55.012U1) as they are factory-installed.
How does this handle power loss?
The unit includes a spring-return fail-safe that ensures the valve closes immediately (typically < 0.8 seconds) when power is cut, protecting the combustion system.
