Assignee:

Honeywell International Inc. - Morristown NJ

International Classification:

F16K 1/22

US Classification:

251308, 251305, 251306, 251366

Abstract:

Butterfly valves assemblies are provided that include a flowbody, a butterfly plate, an actuator and an upper chimney and a lower chimney disposed within the flowbody. The flowbody has an inner surface defining a channel. The butterfly plate is disposed in the channel, is rotationally mounted to the flowbody, and has an outer periphery. The actuator has an actuator output shaft that is coupled to the valve shaft via a serrated spline coupling. The upper chimney and the lower chimney are configured to include bearing assemblies that constrain radial loads and thrust loads exerted upon the valve shaft and minimize misalignment of the serrated spline coupling.

Abstract:

Butterfly valves are provided that include a flowbody, a butterfly plate, and a coating. The flowbody has an inner surface defining a channel. The butterfly plate is disposed in the channel, is rotationally mounted to the flowbody, and has an outer periphery. The coating is disposed on at least a portion of at least one of the flowbody inner surface and the butterfly plate outer periphery and is made of a material formulated to abrade upon friction contact with an adjacent surface and to maintain structural integrity when subjected to pneumatic forces of at least 600 psi.
