SKP55.001E1 Siemens Controller

Overview

The Siemens SKP55.001E1 is an electro-hydraulic actuator designed for use with Siemens VG series gas valves. It functions as a differential pressure air/gas ratio controller, providing safety shut-off and precise pressure regulation in one unit. This actuator is engineered to maintain a constant 1:1 ratio between gas and air pressure, ensuring optimal combustion efficiency even when air flow is disrupted or combustion chamber back pressure fluctuates. Its modular design simplifies gas train assembly by reducing the number of required components and fittings.

Features

• Combines safety shut-off, constant pressure regulation, and differential air/gas ratio control
• Integrated adjustable auxiliary switch for position feedback
• 1:1 differential pressure ratio maintained across the entire operating range
• Automatic compensation for variations in combustion chamber back pressure
• Slow opening and fast closing (less than 0.8 seconds) for enhanced safety
• Visual stroke position indicator and “power on” indication light
• Modular 360 degree rotation for flexible installation and field wiring
• Durable construction with a protection rating of IP54
