“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]).”
Somas ball segment valves type KVTW LN (KVTF LN) with a centrically mounted shaft and KVXW LN (KVXF LN) with an eccentrically mounted shaft were developed to reduce noise levels.
The reduction in the noise level is achieved by the installation of a noise-reducing device. The noise-reducing device is mounted behind the ball segment and consists of several steel rods in a specific arrangement. These steel rods distribute the pressure drop over several stages. This reduces the noise level and prevents any cavitation.
The KVTW LN and KVXW LN are supplied as wafer type valves and the KVTF LN and KVXF LN as flange type valves.
“The Somas ball segment valve type KVTF is a flanged ball segment valve with a centrically mounted shaft and the KVXF has an eccentrically mounted shaft.
The valve housing consists of one piece and has a full bore. 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 / KVTF are basis weight valves with a special seat for low torque requirements and offered in combination with a step motor as an accurate control valve. The control valve unit consists of a balanced valve with a drive and control element.
The Somas basis weight valve is used in the paper industry.
