Segmented ball valve
Segmented ball valves which feature a segmented ball and eccentric design are widely used for throttling or on-off operation for many different applications in the process industries. The segmented ball provides a non-restrictive flow path through the valve allowing for high capacity flows. The construction can be side entry type or top entry type. B3 segmented ball valves also feature a variety of seals to allow for excellent shutoff and shearing between the ball and seal upon closure.

Design Features
* Long Service Life - The solid HD metal seal construction provides long service life in demanding applications. The constant wiping action of the seal across the ball's sealing surface prevents scale and sludge buildup, and provides excellent service on steam, gases, slurries, and various liquid applications.
* Smooth Valve Operation - Precision machined parts and pressure balanced seal designs allow smooth, precise movement of the ball.
* Sour Service Capability - Materials are available for applications handling sour service. These materials comply with the requirements of NACE MR0175-2002.
* Quick and Easy Maintenance - Ball seal inspection and replacement is done at the valve body inlet without removing the actuator or disassembling the valve. Valve maintenance requires no special tools.
* Structural Integrity - One-piece valve body improves structural integrity of the pressure boundary by eliminating leak paths that could be caused by the gaskets in two-piece, bolted valve designs
