Lined Ball Valves

Lined valves of all types have an isolating layer of material that keeps the media from contacting the valve body, maybe even the valve trim itself. The purpose of the lining is generally to extend the useful life of the valve by eliminating the corrosive effect that may be imparted by media on the valve construction. Lined valves, with no exception I can think of, will have metal bodies. The lining can be any of a number of materials that will be selected based upon resistance to degradation by the process media under consideration.

Lined ball valves deliver the performance of conventional ball valves, coupled with the corrosion protection afforded by an appropriate lining material.

• Low pressure loss
• Quarter turn operation
• Simple automation
• Positive shutoff
• Low to moderate operating torque
• Compact

Options for the ball configuration are available to meet throttling or other requirements. Automation can be accomplished via a range of means. For more information, share your valve and automation challenges with application specialists and leverage your own knowledge and experience with their product application expertise.

Ball valves are a staple of fluid process control, delivering a host of design and performance attributes making them the valve of choice for many applications. When the process involves corrosive fluids, steps must be taken to accommodate the aggressive nature of the media, so that valve trim and body are not prematurely degraded by the intended use.

A good solution for valves exposed to aggressive media is an interior lining of fluoropolymer or other material resistant to the corrosive effect of the fluid. Employing a lining protects the valve metal parts from contact with the fluid, allowing the use of less expensive metals in the construction of valve body and other valve components. In extreme cases, ball valves can be delivered with fluid paths fabricated of ceramic material for superior corrosion and erosion resistance.

Flowserve Atomac is a globally recognized leader in the manufacture of lined ball valves, as well as lined strainers, sight glasses, sampling valves, and check valves. Lined ball valves are available in essentially all the configurations expected of more conventional ball valves, including diverter and control service versions.
