摘要： A packing nut assembly for a control valve having a valve body and a valve stem includes a packing box arranged for operative coupling to the valve body and having a primary bore sized to receive the valve stem and first and second counterbores. The first counterbore is sized to receive valve packing and the second counterbore includes internal threads. A packing nut having a central bore is sized to receive the valve stem and includes a threaded outer surface positioned to engage the second counterbore of the packing box. The packing nut includes an adjustment surface positioned to face the first counterbore, and includes an adjustment head having a plurality of tool-receiving apertures sized to receive an adjustment tool.

摘要： Flexible seals for process control valves are disclosed. An example disclosed seal includes a seal for use with a butterfly valve. The example seal includes a substantially flexible ring-shaped carrier configured to be moveably fixed within the butterfly valve and to surround a flow control aperture therein. The example seal includes a seal stiffener adjacent the substantially flexible ring-shaped carrier to increase the stiffness of the substantially flexible ring-shaped carrier in a first flow direction. The example seal includes a substantially rigid seal ring to engage an opposing surface.

摘要： A control valve of the ball type with bi-directional shutoff capabilities is disclosed. The ball valve including an inlet and an outlet, a ball element and a seal assembly. When closing the valve, the ball element, which is eccentrically mounted on a shaft, rotates to abut the seal assembly. While closed, the seal assembly including a seal housing, a main seal and a resilient member, contacts the ball element at the main seal, while the resilient member biases the main seal toward the ball element. The seal assembly further includes a secondary flowpath between the main seal and seal housing, which is restricted by two unidirectional seal rings.

摘要： A control valve having a seat ring assembly constructed from a unitary piece of material is disclosed. The seat ring assembly may include a base which serves as a valve seat for the valve plug of the valve, and which includes a plurality of exterior threads adapted to rotatably attach to a plurality of interior threads provided within the valve body. The seat ring assembly may also include a post-guided bearing surface to maintain alignment of the valve plug to the valve seat. The seat ring assembly can be secured to the valve body simply by threadably attaching the elements. Moreover, by providing the valve seat and the guide surface as integral parts of the seat ring assembly, manufacturing costs and maintenance requirements are reduced and subsequent seal leak performance is increased.
