摘要： Techniques that enable the installation of a level sensor capable of continuously detecting a level of fluid in a vessel or tank and capable of being integrated in a larger control system. Advantageously, the sensor head of the level sensor can be installed on existing installations with an existing displacer or float and an existing member or rod. The techniques thus enable process plants to easily and affordably replace pneumatic level sensors with a more environmentally friendly option.

摘要： A control valve includes a valve body, a valve seat, and a valve closure member displaceable a closed position and an open position. An attenuation element is provided and includes a plurality of hollow tubes including a first tube, a second tube and a third tube. Each tube includes a flow axis from an open first end to an open second end, and an inner surface defining a flow area and having a cross-sectional shape normal to the flow axis. A second end of the tubes is between the valve closure member and first ends of the tubes along their respective flow axes when the valve closure member is closed. The first tube, the second tube, and the third tube are integrally formed as a single, unitary structure.

摘要： Valve bodies and methods of manufacturing the same are disclosed. An example method of manufacturing a valve body includes forming a first duct extending from a first side of the valve body, forming a first wall in the valve body at least partially protruding from a surface of the first duct, the first wall defining a chamber, forming one or more openings in the first wall to fluidly couple the chamber to the first duct, and forming a second duct extending from a second side of the valve body opposite the first, the second duct fluidly coupled to the chamber.
