Abstract: A high pressure relief valve includes a nozzle that is received within an internal bore of a valve housing. The nozzle has a nozzle body with a bore defined by an outlet bore inner diameter that is less than an inlet bore inner diameter. The nozzle body has a nozzle face defined at the outlet end, and is defined between the outlet bore inner diameter and an outlet bore outer diameter spaced radially outwardly of the outlet bore inner diameter. The nozzle body includes a coupling feature held fixed relative to the nozzle body such that the coupling feature is not moveable relative to the nozzle body. The coupling feature is configured to couple the nozzle body to the closure sleeve that surrounds the outlet end. At least one retaining feature prevents the coupling feature from being uncoupled from the closure sleeve.

Abstract: In one featured embodiment, a closure sleeve for a valve comprises a sleeve body surrounding a center axis and defined by an overall length extending from an upstream end to a downstream end. The sleeve body has an internal cavity that is enclosed at the downstream end and is open at the upstream end. The internal cavity is defined in part by a piston contact surface that is defined by an inner diameter. The piston contact surface is configured to slide against a piston to be received within the internal cavity, and a ratio of the inner diameter to the overall length is between 1.0 and 1.5.
