SKP25.001E2 Siemens Actuator

Overview

The Siemens SKP25.001E2 is a high-performance electro-hydraulic actuator designed to provide both safety shut-off and gas pressure regulation for industrial and commercial burner systems. This multifunctional unit serves as a constant pressure governor, ensuring a stable gas supply by maintaining a consistent downstream pressure regardless of fluctuations in the inlet pressure. It is engineered for single-stage operation and includes an integrated end switch (Proof of Closure) for enhanced system safety and feedback.

Features

• Combined safety shut-off and pressure regulating functions in a single compact unit
• Integrated end switch for electrical indication of the fully closed valve position
• Damped opening and rapid fail-safe closing in less than 0.8 seconds upon power interruption
• Visible position indicator and “Power On” light for easy monitoring of operation and stroke
• Low power consumption and durable construction suitable for continuous operation
• Modular design allows for 360 degree rotation to simplify field wiring and installation
• Suitable for use with air and gas families I, II, and III
