Ball segment valves type KVT with a centrically mounted shaft, and KVX with an eccentrically mounted shaft are of wafer design. Type KVTF is a flanged version with centrically mounted shaft while KVXF is a flanged and eccentric design. The valves in this data sheet are of top entry design.
Short face to face dimension, low weight and small space requirement make the installation of the these valves very easy. Unique shaft device is designed for torque transmission and gives backlash-free operation with accurate control. The shaft is guided in the valve body and stuffing box sleeve.
The spring loaded seat is available in 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 KVT/KVTF for liquids, media containing impurities etc. For dry and clean media choose KVX/KVXF. In the KVX/KVXF 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.
