An example apparatus includes an actuator casing having a load apparatus to define an upper pressure chamber and a lower pressure chamber. The upper pressure chamber is opposite the lower pressure chamber. A yoke is to couple to the actuator casing to a fluid valve. An internal passageway is formed in a body of the yoke to fluidly couple a control fluid to at least one of the first or the lower pressure chamber. A fluid connector assembly is positioned in the actuator casing to fluidly couple the internal passageway to the upper pressure chamber. The load apparatus is between the internal passageway of the yoke and the upper pressure chamber.

摘要： Remotely readable valve position indicators and related methods are described. An example valve position indicator includes a wireless identifier device coupled to a valve stem or shaft to move with the valve stem or shaft. The wireless identifier device is to convey information indicative of the position of the valve stem or shaft to a remote wireless electronic reader. The example valve position indicator also includes a shielding body to prevent the wireless identifier device from conveying the information to the remote wireless electronic reader when the valve stem or shaft is in a first position and to permit the wireless identifier device to convey the information to the remote wireless electronic reader when the valve stem or shaft is in a second position.

摘要： A fluid pressure reduction device for use with a fluid valve control member movable through the device. The pressure reduction device is formed of a plurality of stacked disks having an outer perimeter and an inner perimeter defined by a hollow center aligned along a longitudinal axis. The disks are formed in a cage assembly for receiving the fluid valve control member within the hollow center along the inner perimeter. The stacked disks include a plurality of longitudinal channels formed in the disk around the inner perimeter. Guide members formed of a metal harder or at least with greater wear resistant characteristics than the disks are provided in each of the longitudinal channels. The guide members are adapted to the inner perimeter for guiding the fluid valve control member in movements through the hollow center for reducing wear on the inner perimeter. It is preferred that the guide members comprise longitudinal rods inserted within each channel. Alternatively, longitudinal weld bead strips can be welded within the channels.
