Datasheet Ball segment valve Si-111 EN Edition: 2012-07 Type KVTF/KVXF Flanged design Nominal pressure PN 40 / PN 50 Nominal size DN 80 - 250 Material Stainless steel and • Control-valve shut-off • High capacity • One-piece shaft gives a torque transmission free of backlash • Excellent tightness irrespective of differential pressure • Easy maintenance The SOMAS ball segment valve type KVTF is a flanged version with centrically mounted shaft while KVXF is a flanged and eccentric design. The valve body is in one piece. Shaft device in one piece for torque transmission free of backlash. The spring-loaded seat is available in three alternative materials (PTFE, PTFE 53 and HiCo). The valves can be used for control, as well as for shut-off applications on practically every type of media within a wide temperature range. Choose KVTF for liquids, media containing impurities etc. For hot, dry and clean media choose KVXF. In the KVX-valve the ball segment is eccentrically mounted and rotates out from the seat when the valve is opened. This reduces the wear on seat and segment. Low noise trim is available as an option. The designation “LN” indicates that the ball segment is equipped with a network of bars that are used to split up the pressure drop across the valve. This results in less pressure recovery, thereby reducing the noise and potential damage due to cavitation. Note! Capacity factors will be reduced for valves with LN-trim Option • LN Noise) (Low Ball segment with low noise trim for high ∆P 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.
