Siemens Combustion SKP15.013U1 Actuator

For industrial burner professionals, the Siemens SKP15.013U1 Actuator is a vital component for high-performance gas train assemblies. Operating on 120V AC, this electro-hydraulic actuator serves as a dedicated safety shut-off valve (SSV), providing slow-opening control and immediate, fail-safe closing in less than 0.8 seconds upon power interruption. Engineered for single-stage gas valve applications, this specific "U1" model (without auxiliary or POC switches) focuses on reliable, straightforward on/off gas valve control. Its modular design ensures a seamless fit with the full range of Siemens VG-series gas valve bodies, from 1/2-inch to 6-inch diameters. With a 360-degree actuator rotation and quick-connect wiring terminals, field installation is efficient in tight service cabinets. The unit features built-in visual position indication and a power-on light, allowing technicians to confirm valve status at a glance without specialized tools.

Key Benefits:

• Universal Compatibility: Mounts directly to any Siemens VG gas valve body, simplifying inventory for large-scale facilities.
• Industrial Build Quality: Features a robust electro-hydraulic mechanism designed for commercial burner applications and process heating.
• Enhanced Field Installation: The 360-degree rotation capability allows for flexible conduit entry and easier wiring in complex boiler rooms.
• Low Power Consumption: Efficient 13.5 VA operation reduces the load on control circuits and supports energy-efficient burner systems.
• Reliable Monitoring: Clear stroke indication and LED power status provide immediate feedback for troubleshooting and maintenance.

Common Questions:

Can I add an auxiliary switch to the SKP15.013U1 in the field?
No, auxiliary switches and Proof of Closure (POC) switches cannot be field-installed. If your application requires end-switch signaling, you must select the appropriate SKP15 model (such as the .011 or .012 versions) at the time of purchase.

What is the typical opening time for this actuator?
The SKP15.013U1 is designed for a slow-opening cycle to prevent pressure surges, typically taking 6 to 10 seconds to reach full stroke, while ensuring an immediate safety shutdown when power is removed.

Is a gasket required when mounting/replacing this on a VG valve?
Standard mounting on a square flange gas valve does not typically require additional gaskets for indoor NEMA 1 environments; however, the AGA66 gasket is required to achieve NEMA 4 protection for outdoor or wash-down conditions.
