Abstract
Valve assemblies and associated methods are disclosed that may include a spool valve and one or more stationary inserts. In some examples, the stationary inserts may be configured to be fixed within a valve bore of a valve body to provide a fluid seal between an outer surface of the insert and the valve bore. Embodiments may also include valve assembly repair kits that may include a spool valve and a stationary insert for repairing a malfunctioning spool valve and methods for installing the same.
