Robust engineering design Self relieving seat technology Low emission stem seal technology High quality Benefits Very long service life Bubble tight shut off Low fugitive emissions Low cost of ownership The Jamesbury™ polymer-seated flanged ball valves provide industry leading performance and reliability. Offered in a wide variety of materials to suit an extensive range of applications these valves are designed and manufactured with all our latest technology and expertise. Unique Sealing The superior performance of Jamesbury ball valves is achieved by the unique design of the seats. The flexible lip seats exert continuous sealing pressure on the ball and automatically compensate for wear and changes in pressure and temperature, yielding positive bi-directional zero-leak shut-off. The stem seal sealing system ensures minimum emissions. Materials Standard products are available with carbon steel body and stainless steel trim or all stainless steel construction. Special body and trim materials such as Alloy 20, Hastelloy® C, and others are available upon request. Forapplications involving chemicals, acids, caustics, and steam we recommend our Xtreme™ seat material, which provides superior lifecycle and sealing performance compared to virgin or filled PTFE. We can accommodate nearly any special customer or application specific requirement.
