Control valve symbol
Thread Content
What are the meanings of the control valve symbols LICVA and LVC in the dimethyl ether reflux tank, and what is the difference between them?
They are all level control valves; the former comes with indication and alarm functions
Based on experience, it is likely that L represents the liquid level, I indicates the indicator, C stands for control, V refers to the valve, and A denotes the alarm. For detailed information, see the letter codes representing the measured variables and instrument functions on the first page of the \"Unified Regulations on the Content and Depth of Chemical Process Design Drawings\"
L Liquid I Indicator C Control V Valve A Alarm
L: LEVEL, not the English word above
The control valve can also issue alarms; is that the code for a transmitter?
Agreed; licva should be the functional symbol for interlocked instruments, while lvc refers to valves. This post was last edited by thn_cn on 2008-1-11 at 12:01.]
Apart from the incorrect explanation for L (which should be liquid), there is also a spelling error: I_-- should be indicator.
It’s the functional symbol of an interlock instrument! I’m not sure what the difference is from the latter! Thank you for your guidance!
LICVA and LVC should be expressed as LICAV and LCV.
