An anti-cavitation valve assembly includes a seat positioned within a fluid pathway between a fluid inlet and outlet of a valve. Spaced apart elongated seat apertures are formed in a circumferential wall of the seat that have a varying opening width along a length thereof to direct fluid flow into an inner seat chamber of the seat. A disc guide is slidably movable relative to the seat and has a wall having spaced apart disc guide apertures formed therein. A tortuous fluid flow pathway is formed as fluid enters through the seat apertures, into the inner seat chamber, and exits through the disc guide apertures to minimize fluid cavitation.
