What do the terms CSO\CSC mean for valves? Is it related to TSO?
It should be the tag number of the valve position switch. . .
CSO is normally open and must not be turned off without permission. \CSC is normally closed and must not be turned on without permission
CS stands for seal. Just like an electricity meter – you know, there’s that thing. . . @jiaguoyun
TSO: Tight Shut Off – a leak-free closed state. CSO: Car sealed open – sealed with lead while in the open state. CSC: Car sealed close – sealed with lead while in the closed state
CSC is the abbreviation for car seal close, meaning sealed shut with a lead seal. CSO is the abbreviation for car seal open, meaning the seal has been broken. Opening and closing lead seals are safety management measures. \"Lead seal closed\" means that the valve, which is sealed with a lead seal, is closed and must not be opened without permission. \"Car seal open\" indicates that the valve, which is sealed with a lead seal, is in an open state and must not be closed without permission. Valves that are sealed with seals (just like those used for instrument calibration) generally should not have their status changed arbitrarily; if such a change occurs, the seal will be damaged, and it is necessary to keep relevant records and re-seal the valve.
Impressive, I’ve heard of it for the first time. Sir, could you show me a photo? Is there any information on this topic? Study*Study*
I don’t have any specific documents on hand; this information is something I found on the Internet. By combining it with the PID diagrams and the actual conditions at the site, I believe it to be accurate, so I’m sharing it here with everyone. I hope it might be useful to you.:)
