“The unique system of a shaft with a clamping coupling was developed by Somas for backlash-free torque transmission and enables extremely precise control behaviour.
The Somas ball segment valves type KVTW with a centrically mounted shaft and type KVXW with an eccentrically mounted shaft are produced in a wafer version. The D-version of the valve is produced with a short length.
The valve is also produced in the A-version with the standard length (see Si-113).
The valve body of the wafer type ball segment valves is produced in one piece. The spring seat is available in three material alternatives (PTFE, PTFE 53 and HiCo [high cobalt alloy]).”
