Control Valve Testing is proving to be a complex Measurement. In general Control Valve Manufacturers are facing practical difficulties for testing large size Valves (typically over 10”) through reputed & NABL accredited Fluid Flow Laboratories - & hence bound to theoretically calculate the Control valve coefficient ‘Kv’& deriving CV values.

We at Nagman Calibration Services LLP have full-fledged facilities, built-in with all necessary Flow parameter measurements that are essential to test the Cv values directly, & to meet the recommended Standards (ANSI/ISA-75.02-1996 and ANSI/ISA-75.01-2002), even for very large size Control valves up 16”.
