SKP25.711U1 Siemens Pressure Regulator

Overview

The Siemens SKP25.711U1 is a specialized electro-hydraulic actuator designed for gas pressure regulation and safety shut-off in industrial and commercial burner systems. This specific model functions as a variable outlet pressure regulator, featuring an integrated SQS67U setpoint adjusting motor to facilitate precise, automated control of low gas pressures. By combining safety shut-off and pressure regulation into a single unit, it simplifies gas train design, reduces the number of required components, and minimizes the overall footprint of the system.

Features

• Integrated SQS67U setpoint adjusting motor for automated and remote pressure setpoint control
• Dual-function design provides both safety shut-off and precise gas pressure regulation
• Electro-hydraulic operation ensures slow opening for controlled ignition and rapid closing in less than 0.8 seconds for safety
• Servo-operated regulating system provides accurate pressure control with virtually zero droop across the burner turndown range
• Modular architecture allows for easy mounting onto any Siemens VG series gas valve body from 0.5 to 6 inches
• Built-in visual position indicator and power-on light for easy monitoring and troubleshooting
• 360-degree actuator rotation simplifies field wiring and installation in tight spaces
