This valve assembly, only available in automated version, uses a combination of two main butterfly valves between flanges connected by a channel forming an air space.
This channel is equipped with a leakage microvalve and an optional air space washing microvalve.
When both valves are closed, the venting of the air space indicates a fault on either of the valves.
