SKP25.003E1 Siemens Actuator

Overview

The Siemens SKP25.003E1 is a high-performance electro-hydraulic actuator designed for use with Siemens gas valves. This specialized unit functions as both a safety shut-off valve and a constant pressure governor, providing precise regulation and reliable fail-safe operation. Engineered for industrial and commercial burner applications, it combines multiple gas train components into one compact device, simplifying system design and reducing the overall footprint.

Features

• Combined safety shut-off and constant pressure regulation in a single unit
• Electro-hydraulic operation ensures a damped, smooth opening and rapid fail-safe closing in less than 0.8 seconds
• Integrated stroke indication provides a visual display of the entire valve travel
• Power-on indication light for immediate status monitoring
• Low power consumption for efficient operation in high-demand environments
• Self-contained hydraulic system with an internal oscillating pump and relief mechanism
• Modular design allows for 360 degree rotation for flexible installation and field wiring
