SKP25.001E1 Siemens Actuator

Overview

The Siemens SKP25.001E1 is an electro-hydraulic actuator designed for use with gas valves in industrial and commercial combustion systems. It functions as a safety shut-off device and a constant pressure governor, providing reliable valve operation and rapid fail-safe closure. This single-stage actuator is engineered to work in combination with various Siemens gas valve bodies to regulate outlet pressure, ensuring precise control and optimal burner performance.

Features

• Combined safety shut-off and constant pressure regulation in a single compact unit
• Integrated end switch (Proof of Closure) for electrical indication of the fully closed position
• Slow opening and rapid fail-safe closing mechanism (less than 0.8 seconds)
• Maintenance-free electro-hydraulic operation with a visible stroke position indicator
• Durable design suitable for gases of gas families I through III and air
• Low power consumption during continuous operation
