SKP25.013U2 Siemens Actuator

Overview

The Siemens SKP25.013U2 is a high-performance electro-hydraulic actuator designed for use with Siemens VG series gas valve bodies. It integrates safety shut-off and gas pressure regulation into a single, compact unit, providing reliable control for industrial and commercial burner systems. Engineered for continuous duty, this 220-230V AC actuator features a modular design that simplifies installation and maintenance by reducing the number of components needed in the gas train.

Features

• Combined safety shut-off and constant pressure regulation in one unit
• Slow opening and rapid fail-safe closing in less than 0.8 seconds upon power loss
• Accurate pressure control with zero regulator droop
• Integrated “Power On” indicator light and visible position indicator for stroke monitoring
• Modular design allows for 360-degree rotation to facilitate easy field wiring
• Ventless pressure regulator certification for increased installation flexibility
• Low power consumption for efficient operation
