1 Datasheet Ball segment valve Edition: Type KVTF-C/KVXF-C Flanged design Short face to face Nominal pressure PN 25 / ASME Class 150 Nominal size DN / NPS 3-16 Material Stainless steel Control- and shut-off valve High capacity One-piece shaft gives a torque transmission free of backlash Excellent tightness irrespective of differential pressure Easy maintenance Option KVMF-ball segment with V-groove for high fibre concentrations The SOMAS KVTF-C is a flanged ball segment valve with centrically mounted shaft and KVXF-C is a flanged ball segment valve with eccentrically mounted shaft. The valve body is in one piece. Face to face dimensions in accordance with EN558:2008-series 36 and ISA 75.04S. Shaft piece is also in one piece for backlash free torque transmission. The spring loaded seat is available in three different 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-C for liquids, media containing impurities etc. For dry and clean media choose KVXF-C. In the KVXF-C 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. Ball segment with V-groove is available for use at high fiber concentrations. The V-groove design prevents dewatering at small opening angles. 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.

7 Edition: Further technical information Technical data for the materials used in the SOMAS valves, flange standard, steam data, etc. can be found or ordered on the of the SOMAS website or in sections 6 of the SOMAS catalogue. Actuators and accessories The valves can be fitted with SOMAS manual, on/off or control actuators in accordance with the selection table. The valves will then be delivered as tested units ready for installation. Check the SOMAS web-site or in sections 4 and 5 of the SOMAS catalogue, where positioners, limit switches and solenoid valves are also presented. We can also fit other types of actuators and accessories in accordance with your specification. Option Within the process industry and the energy sector there are a number of applications where process data in combination with standard control valves will end up with problems such as high noise level and erosion. These problems are mostly related to cavitation and high flow velocities inside the valve. Note! By using a standard ball segment valve and add a noise reduction trim many of the above mentioned problems can be solved. See datasheet Si-108 for more theoretical information. For controlling suspensions with high fibre concentrations it can be advantageous to use valves with a V-groove to reduce the risk of de-watering at small opening angles. Capacity factors and remaining factors for valves with LN-trim and valves with V-groove are available in the valve sizing program SOMSIZE.
