Overview
The Siemens SKP75.501E2 is a high-performance electro-hydraulic actuator designed for use with Siemens gas valves. It functions as a safety shut-off device and an air-gas ratio controller, specifically engineered for modulating forced draft gas burners. This model features an extended zero-point offset (bias) range and is built for 230 VAC operation, providing precise fuel regulation and rapid fail-safe closure to ensure combustion safety and efficiency in industrial and commercial burner applications.
Features
- Combines safety shut-off, constant pressure regulation, and air-gas ratio control into a single unit
- Extended zero-point offset range of -4.5 mbar for greater control flexibility
- Integrated end switch (Proof of Closure) to signal the fully closed valve position
- Electro-hydraulic opening mechanism with rapid spring-return closing in less than 0.8 seconds
- Visual position indicator and power-on light for easy status monitoring
- Modular design allowing 360-degree rotation for flexible installation and field wiring
- Durable construction suitable for gas families I, II, and III
