摘要： A fluid control device comprises a valve body, a valve plug, a valve cage, and a sealing ring. At least a portion of the sealing ring is disposed within a gap between the valve plug and the valve cage to provide a seal therebetween when the valve plug is in the closed position. The sealing ring includes an L-shaped cross-section that provides an effective seal regardless of the port diameter of the fluid control device, and thus, reduces the number of types of seals required to be stored in inventory for various applications.

摘要翻译： 流体控制装置包括阀体，阀塞，阀笼和密封环。 密封环的至少一部分设置在阀塞和阀笼之间的间隙中，以在阀塞处于关闭位置时在其间提供密封。 密封环包括L形横截面，无论流体控制装置的端口直径如何，都能提供有效的密封，因此减少了为各种应用而需要存储在库存中的密封类型的数量。

摘要： Apparatus to connect a stem to a valve member and, more particularly, apparatus to connect a threaded stem to a valve member of a control valve are disclosed. An example apparatus includes the threaded stem received in a threaded opening of the valve member and a plug received in an opening of the stem to expand diametrically the end of the stem to secure the threaded stem to the valve member.

摘要： A valve trim apparatus for use with valves is described. An example valve trim apparatus includes a cage having an upper portion removably coupled to a lower portion. A closure member is disposed within the cage and has a first seating surface and a second seating surface. A seal assembly is fixed between the upper and lower portions of the cage. The first sealing surface of the closure member sealingly engages the seal assembly when the closure member is in a closed position to prevent leakage between the closure member and the cage.

摘要： A seal assembly for use with valves having a two-piece cage is described. An example seal assembly includes a body defining a bore extending along an axis to slidably receive a closure member. The body includes a first portion removably coupled to a second portion. The first portion includes a first groove and the second portion includes a second groove. The first and second grooves form a sealing surface when the first portion couples to the second portion. The example seal assembly further includes at least one sealing member disposed adjacent the sealing surface to provide a seal against the closure member and a biasing element to bias the sealing member toward the sealing surface.
