Abstract
Abstract A valve assembly for controlling flow of fluid under pressure through a portion of a fluid-moving structure is formed of a plurality of elements adapted to be arranged to form either an intake or an exhaust valve assembly and to form single- or multiple-deck valve assemblies. The valve assembly includes one or more decks each having a seat member and a cage member with a plurality of valve member resiliently mounted therebetween to open and close fluid flow passages through said respective deck in response to differential pressure. The cage members each have a guide bore for each valve member and a vent passage through the cage member for each guide bore and a wafer valve member is mounted within each guide bore at the vent passage for cushioning movement of the respective valve member and for effecting positive seating thereof. In multiple-deck valve assemblies a spacer member is mounted between and in engagement with facing surfaces of adjacent decks for controlling the direction of flow of fluid through the assembly.
