At the top of tanks where the Radar level instrument is located, is there a requirement of TRUNION type ball valve to provide isolation of the instrument??
Whether normal ball valve can suffice?? or if there`s no requirement of this ball valve at all??
On what basis these valves are specified??(like for high pressure tanks..etc)
