Abstract
Slotted, fluid-flow dividing therefor employed in a fluid valve not only to reduce noise but also to shift the frequency spectrum of the noise energy. The slotted therefor is formed integrally with the valve seat. Additionally, the cross-sectional shape of the slots may be varied to more precisely control the lift characteristic of the valve.
