ABSTRACT:
A low-noise valve has a body with a fluid inlet to receive pressurized fluid, an oulet and a fluid passageway extending between the inlet and outlet. Located in the passageway are a number of spaced throats. The valve also includes a movable stem with a number of plugs each adapted to be closely received by a corresponding throat. Each plug includes a plurality of circumferential alternating grooves and lands, the lands being closely spaced within the throats to create a plurality of flow restrictions each incrementally restricting fluid flow when the stem is at a minimum flow position. Movement of the stem toward a full open position sequentially removes the lands from the throat to reduce restriction of said fluid flow in stages.
