Features
Technical Data

▪ Round polished disk guarantees the concentricity of disk and seat. This results in low torque, good sealing and long service life.

▪ Replaceable seat design reduces maintenance cost
▪ Two-stage sealing design effectively prevents the medium from leaking. Primary seal is provided by preloaded contact between flatted seat surface and rounded polished disc-hub area. Secondary seal is formed by the interference fit of seat/shaft/hub.

▪ Top built-in bearing provides the best support, reduces friction and lengthens the service life
▪ Self-adjustable dual-V gland packing, with the automatic compensation and the two-way sealing characteristics, prevents passing through the stem into the body
▪ Molded-in O-ring provides positive flange sealing and eliminates the need for gaskets. With positioning hole, for convenient installation and centering between the flanges
▪ ISO 5211 top mounting plate available, for easy actuation
