Anyone have a reference for pressure drop for low pressure (1/2") nat gas through lubricated plug valves? CV or equiv length. Specifically 2-1/2" valve.
Hello Katmar, didn't knoow this table existed, thank you!
Otherwise I agree with you: using a 'standardized table' instead of the manufacturors figures could of course land you out with a systematic fault: all figures either too high or too low. Ergo sum across system too high or too low, without knowing which way and how much.
(But any approximate figures better than no figures and no thoughts!)
