The valve is based on the renowned AVK series 46 design with long steel spigot ends for gas applications. The purge pipes welded on the top of the valve spigot ends are leading towards the top of the valve. The purge pipes are assembled with CE approved ball valves and blind flanges.
The purge points make it possible to:
- Purge residual gas in an isolated pipeline section allowing safe maintenance, repair or extension of the pipe system
- By-pass the isolated section to ensure continuous gas supply
- Detect leakages in the pipeline by measuring the pressure by means of pressure gauges
