Datasheet Ball segment valve Si-105 EN Edition: 2012-07 Type KVT/KVX Wafer design Nominal pressure PN 100 Nominal size DN 25/5 - 150 Material Stainless steel and • Control-valve shut-off • High capacity • Ball segment and shaft made in one 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 of wafer design. The valve body is made in one piece for sizes DN 25/5 up to DN 50, while DN 80 up to DN 150 has a split body design. 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.
