1. A valve cartridge comprising:
a pre-assembled body including:
a first portion having a first surface;
a second portion having a second surface, the second surface opposite the first surface with respect to a first direction; and
an outer sleeve that partially receives both the first portion and the second portion therein securing the first portion relative to the second portion such that an entirety of the outer sleeve is positioned between the first surface and the second surface with respect to the first direction, wherein the pre-assembled body defines a through hole extending from an inlet provided in the first surface to an outlet provided in the second surface along an axis that is parallel to the first direction; and
a poppet assembly positioned within the through hole between the first surface and the second surface, the poppet assembly including a poppet member and a biasing member both positioned between the first surface and the second surface, and the poppet assembly coupled to the pre-assembled body such that when installed and in operation the poppet assembly is able to transition from a first configuration in which a first portion of the poppet member is enclosed within the first portion, a second portion of the poppet member is enclosed within the second portion, and fluid flow with a pressure greater than 20,000 psi through the through hole is blocked to a second configuration in which fluid flow with a pressure greater than 20,000 psi through the through hole is permitted,
wherein transition from the first configuration to the second configuration includes movement of the poppet member along the axis.
