SKP15.012U1 Siemens Actuator

Overview

The Siemens SKP15.012U1 is an electro-hydraulic actuator designed for use with Siemens VG series gas valve bodies. It provides a safety shut-off function for industrial and commercial burner applications by opening slowly when powered and closing immediately (in less than 0.8 seconds) when power is interrupted. This specific model features an integrated Proof of Closure (POC) switch and an adjustable auxiliary switch, making it a comprehensive solution for monitoring valve position and controlling secondary equipment. Its modular design allows it to be used with a wide range of valve sizes from 1/2-inch to 6 inches, reducing the need for multiple specialized components.

Features

• Safety shut-off function with fast-closing and slow-opening characteristics
• Integrated Proof of Closure (POC) over-travel switch to signal the fully closed position
• Adjustable auxiliary switch for additional control between 40% and 100% of the stroke
• Visible position indicator and power-on indication light for real-time monitoring
• Modular design with 360-degree actuator rotation for flexible field installation
• Low power consumption of approximately 13.5 VA during operation
• Quick connect wiring terminals to simplify electrical installation
• Durable construction suitable for a wide range of ambient operating temperatures
