SKP75.001E1 Siemens Actuator

Overview

The Siemens SKP75.001E1 is an electro-hydraulic actuator designed for use with Siemens gas valves to provide safety shut-off and air-gas ratio control in industrial and commercial burner systems. It functions as a ratio pressure governor, automatically adjusting gas pressure based on combustion air pressure to maintain a constant ratio across the burner’s entire load range. This integrated design eliminates the need for a separate constant pressure regulator, simplifying gas train configurations and reducing overall installation size and weight.

Features

• Combined safety shut-off and ratio pressure regulation in a single compact unit
• Integrated end switch (closed position indicator) for safety feedback
• Fast-closing fail-safe mechanism (less than 0.8 seconds) upon power interruption
• Adjustable gas-air ratio range from 0.4:1 to 9:1
• Automatic compensation for fluctuations in combustion chamber back pressure
• Visual position indicator and “power on” LED for easy monitoring
• Modular design allows for 360-degree rotation to facilitate field wiring
• Low power consumption (typical 13.5 VA)
• Suitable for use with a wide range of Siemens valve bodies (VGG, VGF, VGD, etc.)
