KVT LN Ball segment valves

SOMAS Instrument

Segment ball valves with one-piece body design are similar to models KVTW and KVXW, but with added noice reduction device which splits pressure drop across valve.

Avaliable for nominal diameters DN50 to DN400 at pressure up to 50 bar.

Within the process industry and the energy sector there are a number of applications where process data in combination with standard control valves will result in problems such as erosion and high noise level. These problems are usually related to high flow velocities or pressure drop within the valve caused by the severe nature of a given process’s requirement. By using a standard ball segment valve and adding the SOMAS noise reduction device to its segment, many severe noise-producing applications can be solved.

The valve body is of one-piece design. The shaft device is also in one piece for torque transmission free of backlash. The spring-loaded seat is available in three alternative materials (PTFE, PTFE 53 and HiCo).

Noise reduction is achieved through a low noise trim. This trim is mounted directly to the segment and consists of a number of bars located in a specific pattern 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. In addition the “LN” trim can tolerate media containing a small amount of fibers or particles.

Ball segment valves type KVTW LN and KVTF LN, with centrically mounted shaft and KVXW LN and KVXF LN with eccentrically mounted shaft, are designed to reduce noise. KVTW LN and KVXW LN are of wafer design while KVTF LN and KVXF LN are flanged valves.
