FluoroSeal - Lined Butterfly Valves Brochure

Due to its specially contoured disc profile, the FluoroSeal fully PFA-lined butterfly valve offers high flow rates with minimal pressure drop throughout the entire range of disc rotation. Positive, bubble tight, bi-directional shut off is assured due to the elastomeric energized seat. With a standard live-loaded stem seal, tight control of fugitive emissions to atmosphere is maintained in both high cycle applications and those applications with temperature gradients. An engineered atmospheric seal at the stem prevents the ingress of foreign material into the packing chamber. Low operating torque is achieved via precision shaft bearings in combination with the spherical seat design.
