Patent number: 11959557Abstract: An evacuation unit is configured to remove entrapped fluid from a flow control. These configurations may incorporate devices that can passively discharge fluid in response to loss of system pressure. These devices may use gravity or spring-assist as mechanisms to move fluid out of spaces in the device. This feature mitigates risks that the entrapped fluid freezes and expands, which can cause damage to metal components and lead to extensive downtime of process lines. As an added benefit, the features can reduce product costs or complexity because the proposed designs avoid the need for additional, peripheral “accessories,” like pumps or heating elements, resident at the location of the flow control.Type: GrantFiled: August 31, 2022Date of Patent: April 16, 2024Assignee: Dresser, LLCInventors: Rajesh Krithivasan, Richard John Klimas, Jr., Jason Glen Knudson

Patent number: 11624380Abstract: A valve positioner for use on a process control valve or “valve assembly.” The process control valve may include a pneumatic actuator and a valve having a closure member coupled with the pneumatic actuator and moveable relative to a seat. The valve positioner may couple to the pneumatic actuator to provide a pneumatic signal to set a position of the closure member relative to the seat. An accelerometer may couple with the valve positioner. The accelerometer may generate data in response to orientation of the valve positioner. In one implementation, the configurations can use this data to ensure proper visualization of data on a display. The data also permits the device to properly manage operating modes, like tight shut-off or fully-opened mode, that may prevail due to orientation issues that cause defects in a measured position for a closure member that regulates flow of material through the valve assembly.Type: GrantFiled: November 4, 2020Date of Patent: April 11, 2023Assignee: Dresser, LLCInventors: Anatoly Podpaly, Jagadish Gattu, Mark Edmund Hebert

Patent number: 11598436Abstract: A safety valve is configured for use at temperatures at or above 760° C. (1400° F.). The safety valve includes a closure assembly that can create a self-energizing, metal-to-metal seal. In one implementation, this closure assembly includes a disc with an arcuate finger that circumscribes an axis of fluid flow through a seat. The arcuate finger may extend inwardly toward this axis and downwardly toward the seat. This geometry permits the finger to flex in response to pressure of fluid that impinges on the downstream side of the disc, such flexure causing a first sealing surface on the disc to more forcefully contact a second sealing surface on a seat.Type: GrantFiled: April 14, 2021Date of Patent: March 7, 2023Assignee: Dresser, LLCInventors: Andrew Crosby Roberts, Richard John Klimas, Jr., Nicholas Ray Myers, Robert Stewart McKee, Dien Nguyen, Rick Cole Hunter
