The high-pressure and low-pressure pilots (high / low pilot) reliably protect your pipeline against overpressure and underpressure.
The Fahlke control unit with integrated pressure pilots is connected to the pipeline by means of a connecting line and continuously measures the line pressure.
If one of your defined thresholds is exceeded, the system automatically moves all connected valves into the predefined safe position to protect your pipeline. Fahlke pressure pilots are DVGW tested and feature the response accuracy class AG1. They continuously measure the pressure in your pipeline and switch with response accuracy of 1% relative to your pipeline pressure. Your advantage: You can safely operate your pipeline at the maximum permissible line pressure to maximize transport volumes.
