SKP75.003E1 Siemens Actuator

Overview

The Siemens SKP75.003E1 is a high-performance electro-hydraulic actuator designed for use with gas valves in industrial and commercial burner applications. It functions as a safety shut-off valve and an air-gas ratio controller, maintaining a precise fuel-to-air mixture across the entire load range. By combining safety shut-off, constant pressure regulation, and air-gas ratio control into a single unit, it simplifies gas train design, reduces the number of required components, and allows for the use of smaller diameter valves.

Features

• Integrated safety shut-off and air-gas ratio control in one compact device
• Slow-opening and fast-closing (< 0.8 seconds) safety functionality
• Automatic compensation for fluctuations in combustion air temperature and combustion chamber back pressure
• Visible stroke position indicator and power-on indication light
• Modular design allowing for 360-degree rotation for flexible installation and field wiring
• Adjustable gas-air ratio from 9:1 down to 0.4:1 with ratio bias adjustment
• Maintenance-free operation with no mechanical wear or play to cause drifting
