ABSTRACT:
An improved cage assembly for ball check valves includes an insert comprising a unitary structure formed from STELLITE.RTM. having a passageway therethrough. A ball is positioned in the passageway of the insert for movement between two positions one of which secures the passageway against the flow of fluids therethrough. The insert is positioned in an insert receiving cavity formed in the lower end of an upstream housing. A downstream housing has a shoulder which engages the insert to secure the insert in the cavity. The downstream housing is secured to the upstream housing by friction welding or by inertia welding.
