What is cv of control valve
Answers were Sorted based on User's Feedback
Answer / sheik muhammed
flow coefficient of control valve.its calculated by the
given below formula:
CV = Q/(P/SG)^1/2
where:
CV -flow coefficient
Q -flow of liquid
P-pressure drop across the flow
SG-specific gravity of the liquid
CV=1.17KV => KV=.86CV
KV is metric unit of CV

Answer / waqas
The Cv is actualy the Flow Coefficient of control valves.
It actually measures the friction experienced by a fluid as
it moves through some pipe / valve. The standard definition
of Cv is:
"the flow of water through a valve at 60 oF in US
gallon/minute at a pressure drop of 1 lb/in2."
