SKP75.013U2 Siemens Actuator

Overview

The Siemens SKP75.013U2 is a high-performance electro-hydraulic actuator designed to provide safety shut-off, constant pressure regulation, and air/gas ratio control for industrial and commercial burner applications. This compact unit simplifies gas train design by performing multiple functions that would otherwise require separate components, thereby reducing the overall size and weight of the system. The SKP75.013U2 is engineered for 230V operation and features a modular design compatible with the full range of Siemens VG series gas valves from 0.5 to 6 inches.

Features

• Safety shut-off, pressure regulation, and air/gas ratio control integrated into a single unit
• Electro-hydraulic operation with slow opening and rapid closing in less than 0.8 seconds
• Adjustable gas-to-air ratio range from 0.4:1 to 9:1
• Automatic compensation for combustion chamber back pressure and air temperature fluctuations
• Visible position indicator and power-on status light for easy monitoring
• Modular design allows for 360 degree actuator rotation to facilitate field wiring
• Low power consumption during continuous duty operation
• Robust construction suitable for industrial environments with an IP54 protection rating
