Abstract
In accordance with at least one aspect of this disclosure, a retaining clip system for retaining an alignment of a valve disc within a valve housing can include, a c-shaped retaining clip configured to be disposed on a shaft of the valve and a shim pack including a plurality of shims configure to axially bound the retaining clip on the shaft.
Claims15
A valve system, comprising:
- a first valve configured to connect to one or more additional valves, including:
- a first housing having a first inlet and a first outlet with a cylindrical flow path defined between the first inlet and the first outlet along a flow axis, wherein a diametral plane is defined diametrically spanning the cylindrical flow path;
- a first connecting flange extending from the first housing via a first housing extension in a first direction configured to connect the first valve to a second valve and a second housing flange extending from the first housing via a second housing extension in a second direction opposite the first direction configured to connect the first valve to a third valve or a connect the first valve to a structure;
- a first valve disc mounted to a first shaft disposed within the first housing along a rotation axis for rotation between a first position of the first valve disc allowing a first flow amount through the cylindrical flow path and a second position of the first valve disc allowing a second flow amount through the cylindrical flow path, wherein a first end of the first shaft extends through the first housing extension and through the first connecting flange configured to connect to a second shaft of a second valve;
- and
- a first retaining clip disposed on the first shaft at a location on the first shaft axially within the second housing extension to axially retain the valve disc within the valve housing.

A retaining clip system for retaining an alignment of a valve disc within a valve housing, comprising:
- a c-shaped retaining clip configured to be disposed on a shaft of the valve;
- and
- a shim pack including a plurality of shims configured to axially bound the retaining clip on the shaft,
- wherein a first shim of the shim pack is configured to set the alignment of the valve disc within the valve housing, wherein the retaining clip is configured to retain the alignment of the valve disc set by the first shim, and wherein at least a second shim of the shim pack is configured to remove axial end play of the shaft within the valve housing, wherein the alignment of the valve disc is a centered alignment within the valve housing.
