Research abstract

THIS PROPOSAL WILL DEMONSTRATE (IN 2" TO 4" SIZE), A NOISE REUCING TRIM THAT CAN BE UTILIZED IN ROTARY CONTROL/ON-OFF BALL VALVES. THIS VALVE TRIM ADDRESSES NOISE AT THE SOURCE. THE BASIC DESIGN HAS A VARIABLE IMPEDENCE TRIM TO CAUSE A HIGH IMPEDENCE AT LOW ANGLES OF OPENING AND LOW IMPEDENCE (VERY LITTLE FLOW RESTRICTION) AT LARGE OPENING ANGLES. IT IS AN IDEAL VALVE FOR PRESSURIZATION/DE-PRESSURIZATION, BLOW-DOWN AND VARIABLE DELTA P-VARIABLE FLOW CONTROL APPLICATIONS. TYPICAL NOISE ATTENUATION RANGES FROM-15-30DBA DEPENDING UPON TRIM ARRANGEMENT AND SELECTION.
