SKP25.011U1P Siemens Actuator

Overview

The Siemens SKP25.011U1P is an electro-hydraulic actuator designed for use with Siemens VG series gas valves. It functions as both a safety shut-off valve and a 1:1 air/gas ratio regulator or zero governor. This specific model features a Proof of Closure (POC) switch and is factory-equipped with a lavender spring, providing a bias range of 0 to -0.6 inches water column. Its modular design allows for integration with various valve bodies, reducing the overall size and complexity of the gas train.

Features

• Dual function safety shut-off and gas pressure regulation in a single unit
• Integrated Proof of Closure (POC) over-travel switch for enhanced safety signaling
• Electro-hydraulic operation ensures slow opening and immediate, fail-safe closing in less than 0.8 seconds
• Visual position indicator and power-on light for easy status monitoring
• Lavender bias spring allows for 1:1 air/gas ratio regulation with a 0 to -0.6 inch wc bias
• Modular design with 360-degree rotation for flexible installation and field wiring
• Low power consumption and durable construction suitable for industrial environments
