1 WAFER PATTERN V-PORT BALL VALVE stainless steel C ont R o L Description Edition Högfors ball sector valve series 5 is specially designed for control applications of various medium like liquids, pulps and steam. 5KC 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 do not last. 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 ball sector valve is a reduced bore valve manufactured in stainless steel throughout with a hard chromed ball sector and Stellite or PTFE seat. The V-port gives an excellent control characteristic which is intermediate between linear and equal percentage. The shaft packing box has tightable graphite seals. Nominal dimensions: DN 5 00 Nominal pressure PN DN 5-00 Pressure difference (ΔP) 1 bar / 0 / 5 / 1 bar Ball seal alternatives Stellite (KC) PTFE (TC) Tightness class ISO 50, EN 1-1 RATE D RATE A * Working temperature of liquid media +0 C -0 C +00 C -0 C Connection Connection between flanges EN109-1, Facing Type B. ANSI B 1.5 Safety Conform to the requirements of the Council Directive 97//EC on Pressure Equipment, marking: Class: gas, group 1. Explosion-proof design is available as per special order. Marking in accordance to ATEX Directive 9/9/EC: group II GD, protection concept of non-electrical components: c T. *) The max pressure difference depends on the working temperature.
