SOMAS Butterfly valves have an - advanced triple-eccentric design

Butterfly valvesSOMAS butterfly valves helps to adjust your flow, be it steam, gas, water or other fluids. SOMAS butterfly valves can handle it.

Our 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. 

SOMAS metal-seated butterfly valves of type VSS and MTV bears a historical relationship to the very first valves manufactured by us. Both valves have an advanced triple-eccentric design. The design of the seat and the 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 our 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.

Dimensions up to DN 1200, pressure classes PN10 - 100 and the universal design allows for manufacture in many different materials and enables us to cover most applications in the process industry.

The butterfly valve is useful for clean as well as contaminated media; fluids, gasses and steam. For control installations the valve is fitted with SOMAS pneumatic actuator and positioner.

For manual actuation the valve is fitted with a hand lever or gear.
