摘要
An example valve includes: (i) a housing defining a first longitudinal cavity therein; (ii) a sleeve disposed in the first longitudinal cavity coaxial with the housing, where the sleeve defines (a) a first port at an end of the sleeve, (b) a second port disposed on an exterior peripheral surface of the sleeve, and (c) a second longitudinal cavity therein, where an interior peripheral surface of the sleeve defines a first portion that is tapered at a particular angle and a second portion adjacent to the first portion, where the second portion has two edges forming a corner that defines a seat; and (iii) a poppet mounted within the second longitudinal cavity and configured to move axially therein.
