Swagelok Expands Its Line of Medium-Pressure Ball Valves

Request free information via our Reader Service Web site at

Engineers at Swagelok, Solon Ohio (, have expanded the company’s FKB line of medium-pressure ball valves by adding one capable of handling pressures up to 15,000 psig. The 8FKB two-way ball valve features a 316 stainless-steel body with reinforced PEEK seals. It operates in temperatures from 0 to 250°F (–17 to 121°C). And users have a choice of several O-ring materials, including nitrile, fluoroelastomer, and perfluoroelastomer.

It takes relatively little torque to actuate the valve, and if pneumatic actuation is required, the company makes ISO-5211-compliant actuators. The positionable handle gives users flexibility in laying out control panels by reducing clearances with other components.
