Control valves, located in short pipes, are operated in a throttled condition to empty and refill individual lengths of pipe lines. The noise level generated by the conventional valves, headers and associated piping during operations can be as high as 140 dBA. A case study, involving the design of control valves for a proposed transfer facility is presented. Applicable noise guideline procedures and feasible noise control measures are highlighted. The cost estimates of the noise control measures are also discussed ER -
