control valves versus self acting regulators
control valves versus self acting regulators
(OP)
Hi, While sizing and selecting a control valve I understand that the term Cv is used and this is calculated using ISA 75.01 standard for valve sizing.However for a regulator there are no such standards and capacity of a regulator is determined from the flow rates published at certain droop. If both regulators and valves are used on similar applications then why two different sizing methodology? Any thoughts
