The Siemens SKP series provides high-precision, modular control for VG series gas valves. Selecting the correct actuator model is critical to achieving specific burner performance—ranging from simple on/off safety shutoff to complex air/gas ratio control.
| Actuator Series | Primary Function | Typical Application |
|---|---|---|
| SKP15 | On/Off safety shutoff. | Basic safety interlocks. |
| SKP25 | Pressure regulation and safety shutoff. | Downstream pressure control. |
| SKP55 | Air/gas ratio control. | Precise combustion balancing. |
SKP15.013U2 — Standard On/Off Safety Shutoff
SKP15.013U2: Electro-hydraulic actuator designed for fast-acting safety shutoff.
Voltage: 120VAC operation for standard industrial burner controls.
End Switch: Integrated auxiliary switch for proof-of-closure feedback.
SKP55.012U2 — Air/Gas Ratio Controller
SKP55.012U2: Advanced actuator that modulates gas flow based on air pressure signals.
Combustion Efficiency: Maintains optimal fuel-to-air ratios for cleaner burning.
Compatibility: Mounts directly to VGD or VGG series valve bodies.
Diagnostic Tip: SKP actuators are electro-hydraulic. If your actuator is not opening, check for trapped air or low hydraulic fluid pressure before assuming electrical failure. A sluggish response is often the first indicator that the internal hydraulic seal is failing.
Reliable combustion depends on the accuracy of your fuel-to-air ratio and the speed of your safety shutoff. SKP actuators are the workhorses of the burner train; replacing aging actuators with current models eliminates drift in pressure regulation and ensures your system shuts down within mandated time limits during a fault condition.
