Siemens Combustion SKP55.011U1 Actuator
The Siemens Combustion SKP55.011U1 Actuator is a professional-grade electro-hydraulic solution designed for precise differential air-gas ratio control in industrial and commercial burner systems. Operating on a 120V power supply, this actuator integrates safety shut-off functions with advanced pressure regulation to maintain a 1:1 ratio between combustion air and gas. By utilizing dP/dP ratio control, the unit automatically compensates for fluctuations in combustion chamber back pressure and air flow disruptions, ensuring high combustion efficiency and stable flame patterns. This specific model features a factory-installed Proof of Closure (POC) switch, providing essential end-of-stroke verification for safety-critical applications. The modular design allows for 360-degree rotation, simplifying field wiring and mounting on Siemens VG series gas valves. Engineered for reliability, the SKP55.011U1 provides a slow opening stroke and an immediate fail-safe closure in under 0.8 seconds upon power interruption, reducing gas train complexity by eliminating the need for separate upstream regulators.
Key Benefits- Integrated Safety & Control: Combines safety shut-off, constant pressure regulation, and air-gas ratio control into one compact unit to reduce footprint.
- Verification Features: Includes a Proof of Closure (POC) switch and a visible stroke position indicator for immediate operational feedback.
- Application Versatility: Ideal for recuperative burners with preheated air and systems with variable air or gas nozzle openings.
- Efficient Installation: Modular assembly mounts directly to VG valve bodies (1/2" to 6") using a four-screw flange, requiring no additional gaskets.
- Zero Offset Performance: Servo-operated regulating system delivers virtually zero droop across the full burner turndown range.
What is the primary function of the dP/dP control in this actuator?
It functions as a 1:1 differential pressure ratio regulator, adjusting gas pressure to match sensed air pressure, maintaining a constant fuel-to-air mixture regardless of volume changes.
Can this actuator be used with non-Siemens valve bodies?
No, the SKP55.011U1 is specifically designed to mount to the square flange of Siemens VG series gas valves, including VGG, VGF, VGD, and VRD models.
Does the POC switch provide a dry contact for the burner management system?
Yes, the Proof of Closure (POC) switch provides a signal to the burner control indicating the valve is fully closed, which is a requirement for many safety interlock sequences.
