Abstract
Control valves are one of the major sources of noise generation in hydraulic systems. A valve design that controls the factors that trigger noise during flow throttling is discussed in this paper. The proposed valve geometry avoids noise generation primarily by maintaining laminar flow and avoiding cavitation and boundary layer separation through the flow passage. The valve design consists of a variable annular tapered configuration that controls pressure and flow quietly. Experimental verification conducted in a two-way valve shows the effectiveness of the valve design in maintaining airborne noise levels below 40 dbA at high pressure and high flows.
