ALARM MANAGEMENT OF MEDICAL GAS PIPELINE SYSTEM.
Full bore ball valves to allow instant shut-off of main, risers or branch lines of a Pipeline system.
These are de-greased, pressure tested and blown clean. End fittings made of brass are provided to
facilitate joining with copper line pipes by brazing or soldering without damaging seal components
of valves
