SKP25.203E2 Siemens Pressure Regulator

Overview

The Siemens SKP25.203E2 is a high-performance electro-hydraulic actuator designed for use with Siemens gas valves. It serves a dual purpose as a safety shut-off valve and a constant pressure regulator, ensuring precise control and rapid fail-safe closure in industrial and commercial combustion systems. The actuator’s modular design allows it to be easily integrated with a wide range of Siemens valve bodies, providing a compact solution for managing gas pressure and flow in burner applications.

Features

• Combined safety shut-off and constant pressure regulation in a single compact unit
• Two-stage opening and closing mechanism for controlled gas flow
• Electro-hydraulic operation with a fail-safe spring-return closure in less than 0.8 seconds
• Integrated stroke indication provides a clear visual of the valve’s position
• Accurate pressure control characteristics with zero regulator droop (offset)
• Maintenance-free design with durable construction for long-term reliability
• IP54 protection rating for resilience in industrial environments
