C ont R o L Description Edition Högfors ball sector valve series 55 is specially designed for control applications of various media like liquids, pulps and steam. 55KC is used for sticky and crystallizing mediums, because of cleaning function of metal seat for both control and on/off applications where std PTFE seated valves does not lasting. If the medium contains solid particles, the geometry of metal seat and segment will warranty better function as std. valves. These valves are tight to one direction which is shown by an arrow according to EN 1-1. The sector ball valve with flanges has a full bore design. The two piece body, v-port ball and stems are. The shaft packing box has tightable graphite seals.
