SKP75.001E2 Siemens Actuator

Overview

The Siemens SKP75.001E2 is a high-performance electro-hydraulic actuator designed for use with Siemens gas valves. It functions as both a safety shut-off valve and a ratio pressure governor, providing precise control of gas pressure based on combustion air pressure. This ensures a constant air-gas ratio across the entire burner load range, making it an essential component for modulating forced draft gas burners in industrial and commercial combustion systems.

Features

• Combined safety shut-off and air-gas ratio pressure regulation in a single compact unit
• Slow opening and rapid fail-safe closing mechanism (less than 0.8 seconds upon power loss)
• Integrated end switch (closed position indicator) for enhanced safety monitoring
• Low-fire and excess-air biasing adjustments for simplified commissioning
• Durable design suitable for gas families I, II, and III, as well as air
• Plug-in connection facility for easy electrical installation
