Abstract: Methods and apparatus are provided for retaining a hinge shaft of a check valve with a bushing. The check valve includes a valve body defining a flow passage therethrough; a hinge shaft; a bushing coupled to the valve body and welded to the hinge shaft; and a closure element pivotally mounted on the hinge shaft for opening and closing the flow passage.

Abstract: A bearing assembly comprises an inner ring and an outer ring assembly having an upstream face and a downstream face. The outer ring assembly comprises an outer ring rotatably coupled to the inner ring, and a plurality of rolling elements that resides between the inner ring and the outer ring. At least one flow bypass channel extends through the outer ring assembly.

Abstract: A check valve includes a valve body defining a flow passage therethrough; a hinge shaft mounted on the valve body; a closure element pivotally mounted on the hinge shaft for opening and closing the flow passage; and a pin secured to the valve body and received by the hinge shaft.

Abstract: A valve assembly is provided including at least one pneumatic component and a pneumatic tube assembly fixedly coupled to the at least one pneumatic component. The pneumatic tube assembly includes a pneumatic tube and at least one tube retaining plate. The at least one tube retaining is fixedly coupled about the pneumatic tube by a weld or brazing process. The at least one tube retaining plate further includes a portion positioned in bonding engagement with a bonding surface of the at least one pneumatic component. A retaining bolt mechanically retains the at least one tube retaining plate to the bonding surface. The retaining bolt and the at least one tube retaining plate provide a bonding path between the pneumatic tube and the at least one pneumatic component.

Abstract: A pressure pickup probe assembly includes a probe housing, a plurality of openings, and a pickup probe. The probe housing is configured to be mounted within, and extend at least substantially across, a flow passage. The probe housing further includes at least an inner surface and an outer surface. The probe housing inner surface defines at least a plenum therein. The plurality of openings is formed in the probe housing, and each opening extends between the probe housing inner and outer surfaces and is in fluid communication with the probe housing plenum. The pickup probe is disposed at least partially within the probe housing, and has at least a first end, a second end, and a bore extending between the first and second ends and that is in fluid communication with the probe housing plenum.
