Abstract: A method of manufacturing a valve of a tool for use downhole includes changing a flow characteristic of the valve. A load is applied to a first nozzle secured in a housing of the valve via a first release member, wherein a magnitude of the load is greater than a release threshold of the first release member, to release the first release member. The first nozzle is removed from the housing, and a second nozzle is secured in the housing via a second release member.

Abstract: An indexing valve system includes a tubular having an inner surface portion defining a passage portion, a first plurality of indexing components provided on the inner surface and a second plurality of indexing components provided on the inner surface portion. A valve sleeve is arranged in the passage portion. The valve sleeve includes a first plurality of indexing elements that selectively engage with the first plurality of indexing components, a second plurality of indexing elements that selectively engage with the second plurality of indexing components, and an inner surface section defining a passage section. The inner surface section includes a plurality of indexing step members. An insert extends into the passage section. The insert includes an outer surface supporting an indexer that selectively engages with the plurality of indexing step members to shift the valve sleeve between the first plurality of indexing components and the second plurality of indexing components.

Abstract: A downhole tool, a nozzle assembly for the downhole tool and a nozzle. The nozzle assembly includes an orifice in a housing of the downhole tool. The orifice has a housing groove. A nozzle is insertable into the orifice, the nozzle including a nozzle groove. A release member secures the nozzle to the housing by disposing a first portion of the release member in the housing groove and a second portion of the release member in the nozzle groove. The first portion is removable from the second portion upon applying a force to the nozzle above a release threshold. The nozzle includes a body having an outlet end, a nozzle groove on a surface of the body for receiving a release member to secure the nozzle within a housing, and a seal groove for isolating the nozzle groove from an environment at the outlet end.
