Datasheet Ball segment valve Si-103 EN Edition: 2012-07 Type KVT / KVX Flanged design Nominal pressure PN 10 Nominal size DN 450 - 700 Material Stainless steel • Control and tight shut-off valve • High capacity • Ball segment and shaft in on piece gives a torque transmission free of backlash • Excellent tightness irrespective of differential pressure The SOMAS ball segment valve type KVT with a centrically mounted ball segment and KVX with an eccentrically mounted ball segment are flanged. The valve body is diagonally splited. Ball segment and shaft are made in one piece. The spring-loaded seat offers excellent tightness also at low differential pressure. The valves can be used for control, as well as for shut-off applications, of practically every type of media within a wide temperature range. Choose KVT for liquids, media containing impurities, sludge and chemicals. For dry media such as steam, gases and acids, choose KVX. In the KVX-valve the ball segment is eccentrically mounted and rotates out from the seat when the valve is opened. This reduce the wear on seat and segment. The SOMAS valves are delivered ready for installation and operation. The valve assemblies are delivered factory tested as complete units with actuators, positioners and accessories.
