Abstract: A flow control device includes a housing forming an inlet passage, an outlet passage, and a fluid passageway between the inlet passage and the outlet passage. A magnetized shaft is positioned entirely within the housing between the inlet passage and the outlet passage and a plurality of vanes are secured to the magnetized shaft and positioned in the fluid passageway. A first wire coil is moveably positioned around a first end of the magnetized shaft, external of the housing, and is linearly moveable in a direction parallel to a longitudinal axis of the magnetized shaft.

Abstract: A fluid control system is provided for controlling flow of a process fluid through a pipeline. The fluid control system can include a valve arranged to control a flow of process fluid, an actuator configured to adjust a position of the valve, and a controller configured to control movement of the actuator. The system may include a switching valve in communication with the actuator and the controller. Further, a solenoid valve may be in communication with a first port of the switching valve. In one example, depending on pressure at the first port of the switching valve, the switching valve is operable in a first state to provide process fluid to the valve controller and permit movement of the actuator and in a second state to block flow of process fluid to the valve controller and block flow of process fluid from the pneumatic actuator.

Abstract: A packing system is disclosed for use with a valve having a bonnet and a flow passage extending between an inlet and an outlet of a valve body. A bore can extend through the bonnet to receive a stem that moves a control member to control flow through the flow passage. A first packing arrangement can be arranged in the bore about a first portion of the stem. A second packing arrangement can be arranged in the bore about a second portion of the stem with the first packing arrangement between the second packing arrangement and the valve body. A bore port can extend through the bonnet and open into an inter-packing volume of the bore between the first and second packing arrangements and can provide fluid communication between the inter-packing volume and the outlet of the valve or other lower pressure area.

Abstract: A sealing arrangement for a valve can include a first seat portion, a second seat portion extending from the first seat portion in a first direction, and an anchor portion extending from the first seat portion in a second direction transverse to the first direction. The anchor portion can include an anchor section having a first sealing surface to provide a first seal within the valve and a convolution section arranged between the first seat portion and the anchor section and including at least one bend that is resiliently compressible in the second direction so that the first seat portion moves in the second direction when the convolution section of the anchor portion is compressed in the second direction.

Abstract: A valve can include a valve body, a rotatable gate, a neck extending from the valve body, a shaft extending from the rotatable gate and through the neck, and a seal assembly configured to rotatably seal the shaft to the neck. The seal assembly can include a first stage seal having a first working temperature and coupled to the shaft at a first stage seal location, and a second stage seal having a second working temperature and coupled to the shaft at a second stage seal location farther from the valve body than the first stage seal location. The first working temperature can be higher than the second working temperature, and the seal locations and the first stage seal can be configured to prevent a second stage operating temperature at the second stage seal location from exceeding the second working temperature.

Abstract: A control valve includes a body having an inlet and an outlet, a valve seat positioned in a passageway of the body between the inlet and the outlet, and a valve plug movable between a closed position and an open position. A trim assembly is disposed within the body to provide guidance for the valve plug and to condition a flow of fluid through the control valve. The trim assembly includes a top portion and a bottom portion. A plurality of ribs extend between the top portion and the bottom portion and a plurality of arcuate lattice segments are removably secured between the top portion and the bottom portion and separated from adjacent lattice segments by a rib of the plurality of ribs. Each lattice segment has a plurality of passages that extend between an inner surface and an outer surface of the lattice segment.

Abstract: Process control instruments having local intrinsic safety barriers and methods of manufacturing the same are disclosed. An example field instrument for a process control assembly includes a non-protection compartment, intrinsically safe circuitry positioned in the non-protection compartment, a protection compartment, non-intrinsically safe circuitry positioned in the protection compartment, and local barrier circuitry positioned in the protection compartment to operatively couple the non-intrinsically safe circuitry to the intrinsically safe circuitry, the local barrier circuitry to prevent the intrinsically safe circuitry from receiving an electrical energy that is greater than an electrical energy threshold from the non-intrinsically safe circuitry.

Abstract: Systems and techniques for accessing and controlling field devices to collect data and convert protocols are disclosed herein. An example system to access a field device includes one or more processors, a transmitter, a wireless network interface controller, and a memory storing instructions that, when executed, may cause the field communicator device to retrieve process parameter data encoded in a field device transmission protocol. The field communicator device may retrieve the process parameter data at a plurality of time intervals from a field device, and the process parameter data may correspond to a process parameter for the field device. The field communicator device may also store at least some of the process parameter data, analyze the process parameter data over the plurality of time intervals to identify a condition of the field device, and transmit an indication of the condition of the field device to a remote device.

Abstract: A valve, such as a ball valve, can include a noise attenuation assembly to control fluid expansion through the valve and provide noise abatement. The valve can include a valve body and a valve stem and the noise attenuation assembly can include a flow control body and a trim body. The flow control body can be coupled to the valve stem and the flow control body can be configured to selectively permit fluid flow through the valve body in an axial direction. The trim body can include a plurality of channels to control fluid expansion during fluid flow through the valve body. The trim body can be engaged with the flow control body at first and second mounting structures of the flow control body to secure the trim within a fluid pathway of the flow control body.
