Pilot-controlled controllers

FL series regulators are used in gas control stations in natural gas transmission and distribution systems, which is filtered before passing through the regulator. FL series regulators are regulators with axial flow, single seat and balanced damper.

This series of “TOP-ENTRY” devices has been designed for a wide range of applications, while maintaining ease of maintenance and in combination with minimal installation dimensions – a safety quick release, a monitor and its own controller are built into one body. The design of the controller and the principle of regulation is based on the FL type.
