SOMAS butterfly valves are made from high-grade stainless steel with a homogenous metal seat as standard. They can be installed by mounting between flanges, with or without lugs. The valves are also available with flanges.
With an advanced triple-eccentric design, the seat design and unique construction of the disc provides for excellent shut-off and more or less eliminate the need for maintenance. The high surface pressure between seat and disc makes the valve useful for pulp applications where the fibers are easily cut. The MTV butterfly valve is the most cost-efficient choice for control- and on/off-applications.
All valves are tested for leakage and meets the requirements of IEC 534-4 Class V for valves with SS 2377-seat (Class VI for valves with PTFE-seat).
The universal design allows for a choice of many different materials in valve manufacture. This broadens the field of application. The metal seat ensures that high-velocity flow will have no effect on the valves tight shut-off ability and allows for many years of operation.
