A compact and lightweight two-piece valve shell (body and pressure seal bonnet) structure reduces possible leakage paths while also providing a top-side ball/stem installation/removal path (when the bonnet piece is not present) to facilitate initial valve assembly as well as subsequent inspection/removal of the ball/stem and other valve internals for conducting valve maintenance without requiring the valve body to be removed from its process connections and without removing the bracket and actuator. Sealing seats can be adjusted in overall length using fluid, vacuum, threads or cams to ease the assembly of the ball inside the body. The sealing seat adjustment can be completed with the ball inside or outside the body cavity.

THERMAL INSULATING SLEEVE LINER FOR FLUID FLOW DEVICE AND FLUID FLOW DEVICE INCORPORATING SUCH LINER
A thermal insulating sleeve liner for fluid flow devices such as valves and piping used in severe industrial applications is preferably additively manufactured (e.g., by 3D printing) to fit into the bore of a protected fluid flow device. Internal interstices and/or external ribs provide added thermal insulation. An integrally formed end-lip or a separate end-cap secures and/or locates the sleeve liner within the protected fluid flow device between different diameter distal and proximal portions of the bore. If internal interstices are sealed they can be vacuumed or pressurized to enhance thermal insulating properties. Fitted dimensions are sufficiently small to prevent ingress of thermally conductive particles circulating in use within the flow path of the protected flow device. A pressure equalizing aperture can be provided on or through the sleeve if needed in some applications.
A monolithic metal thermal insulating sleeve liner for fluid flow devices such as valves and piping used in severe industrial applications is additively manufactured (e.g., by 3D printing) to fit the bore of a protected fluid flow device. Tessellated support structures obliquely extending between inside surfaces of inner and outer shells provide increased resistance to thermal conduction while also providing increased strength against compression forces. Example support structures include an array of four obliquely oriented elongated members mutually intersecting mid-way between the inside surfaces of inner and outer cylindrical shells. A ceramic coating may be applied an inner surface of the sleeve or to the inner surface of the to improve thermal insulation.
Modular skids for severe service applications, and fluid flow device arrangements (modules) for use therein are described. The modular skids and/or the described modules provide for skids that are at least one of, more compact, less costly, less heavy, more serviceable and/or provides for more uptime of the skid than conventional skids.

Sealing cavities created by spaced-apart body-to-bonnet and/or stem-to-bonnet sealing structures can be inertly pressurized to hermetically isolate the sealing structures from ingress/leakage of corrosive process materials.

A ball valve sealing ring is provided for sealing between a ball valve member a valve body. The sealing ring may comprise a ring body having a ball valve member-contacting surface and one or more valve body-contacting shoulders for contacting the valve seat. The sealing ring may comprise a resilient ring core for providing bending resistance. The resilient ring core may be at least partially conical and may have a curved cross-section with a convex side oriented towards the member-contacting surface. The cross section may be of a geometry corresponding to the outer contour of the ring body or shoulders and may have ends bent towards the member-contacting surface. The ring core may also have a plurality of apertures spaced about its circumference. The sealing ring may be elastically deflected upon contact with the valve member. Also provided is a ball valve seating arrangement comprising the aforementioned sealing ring.

Seat arrangement with cavity pressure relief for a ball valve
A ball valve seat arrangement is provided that permits relief of cavity pressure. The arrangement includes a valve body for receiving a resilient annular seat. First passages in the seat provide communication between the valve cavity, and a space formed between the seat and the valve body. When the cavity pressure reaches a certain level, a sealing point between the seat and the valve body is lost. Communication is thereby provided between the space and the valve passage to achieve cavity pressure relief.
