SKP25.711U1H Siemens Pressure Regulator

Overview

The Siemens SKP25.711U1H is a specialized pressure regulating electro-hydraulic actuator designed for use with Siemens gas valves. This high-pressure version is uniquely equipped with an SQS67U setpoint adjusting motor, allowing for motorized variable control of the outlet gas pressure. By combining safety shut-off and precise pressure regulation into a single unit, it simplifies gas train design, reduces the number of required components, and allows for more compact installations.

Features

• Dual functionality provides both safety shut-off and motorized gas pressure regulation in one unit
• Integrated SQS67U setpoint adjusting motor for remote or automated outlet pressure control
• High-pressure design capable of handling demanding industrial gas train requirements
• Slow opening and immediate closing (under 0.8 seconds) upon power interruption for enhanced safety
• Visual stroke position indicator and power-on signal light for easy monitoring
• Modular design compatible with all Siemens VG series gas valve bodies from 1/2 inch to 6 inches
• Built-in proof of closure (POC) switch to signal the valve’s closed position
• Low power consumption and 360 degree rotation for flexible field installation
