  • Publication number: 20230096890
    Abstract: AB STRACT Fluid flow control devices and related systems and methods may include a body or housing and a plug at least partially positioned in the body or housing to define a flow path. In a position of the plug, the plug and the body or housing may collectively define a fluid flow path.

  • Patent number: 11280422
    Abstract: A plug-and-seat valve plug head assembly that resists abrasive erosion includes a hardened plug head, such as a ceramic plug head, attached to a plug stem without any soldering, welding, or braising attachment to the plug head. A diameter of a second portion of the plug head smoothly increases according to a plug diameter profile. A diameter of a first portion of the plug head is everywhere smaller than the plug diameter profile, and is maximal at a location spaced apart from the second portion. A plug head retainer overlaps and closely conforms to the first portion, while presenting an exterior surface that smoothly continues and extends the plug diameter profile. In embodiments, a plug head retainer blank attaches to the plug head retainer, capturing the plug head therebetween. Embodiments apply radial and/or axial stress to the plug head.

  • Publication number: 20210262582
    Abstract: A pneumatically controlled flow booster includes a booster valve plug position sensor that enables control of the flow booster in a feedback loop, for example by a pneumatic valve positioner, thereby providing accurate, high speed, high flow control of both small and large actuator adjustments. Embodiments can accurately control a surge suppression valve over extended valve adjustment ranges and can fully open a surge suppression valve during a trip. The flow booster valve can include a spool and sleeve valve and/or a poppet valve. Embodiments provide bimodal flow boosting, whereby the output flow is less dependent on the valve plug position in a first position range, and more strongly dependent on the valve plug position in a second range.

  • Patent number: 6367774
    Abstract: An element for controlling the fluid flow rate through a fluid valve. The element may include a generally spherical metal housing encasing a cylindrical ceramic insert. The element may also include a cone-shaped metal housing encasing a cylindrical ceramic insert. The cylindrical ceramic insert defines a fluid passageway through the element. The element further includes a coupling mechanism disposed on the metal housing configured for securing a metal actuation shaft to the element. The coupling mechanism provides a high-strength element-to-shaft connection between the metal actuation shaft and a metal portion of the element. The present invention also encompasses a method of manufacturing the element.
