What does CSC stand for in valve category?
The valve on the PSV bypass line must be closed all the time except that the PSV is removed for emergency service. CSO and CSC are NOT the same means of restriction as Locked Open and Locked Closed. Locked valves are shown as LO and LC on PIDs and use either a padlock and chain or a proprietary valve lock. CSO stands for Car Sealed Open.
What is the definition of Lo, LC, CSC?
Does any one here know of an authoritative source (ASME, ISA, NFPA, OSHA, etc..) that gives a definition for the following in one of their standards or codes and the number for that standard or code: LO (Valve Locked Open) LC (valve Locked Closed) CSO (Valve Car Sealed Open)

It does not require a key to operate, just a wire cutter, so it is not as secure as a genuine lock. Both a Locked valve and a Car Sealed valve “should” require a written permit to operate,…

What do the numbers mean on a ball valve?
They are found on the valve body as a number with either WOG or CWP under it. The number represents the pressure rating, ie a 600 with CWP under it would mean the valve is rated to 600 PSI CWP. WSP stands for Working Steam Pressure and defines the pressure of steam in a system that a ball valve can be used in.
