ABSTRACT:
The disk valve employs a conventional valve seat and valve disk arrangement in which the perforations of the valve disk are offset from the perforations of the valve seat. A retainer having venturi-shaped openings is used to reduce flow losses due to eddying of kinetic energy. The valve disk perforations are also formed with flow cross-sections which are greater than the minimum flow cross-section of the aligned retainer openings.
