Abstract:
A check valve includes a valve element and a valve body having a body housing, an annular valve seat insert, a bushing, and a biasing member. The body housing includes an outer circumferential wall extending between an inlet port and an outlet port to define a valve cavity therebetween. The valve seat insert is seated in a body seat surface surrounding the inlet port. The bushing is disposed in the valve cavity and defines a central bore, with the bushing including an outboard end surface axially engageable with the valve seat insert. The biasing member is disposed between a bearing portion of the body housing and an inboard end of the bushing to allow for axial movement of the bushing with respect to the body seat surface. The valve element extends through the bushing central bore and is movable between a closed position and an open position.
