SOMAS butterfly valves, type MTV, MTVF and MTVL, are control, on/off and shut-off
valves. These valves are designed to handle a wide range of liquids, gases and steam
within a broad temperature range.
The MTV valve can be mounted between flanges and also supplied in lugged design.
The valve type MTVF is a full flanged butterfly valve.
The valves have an advanced triple eccentric design including a unique shape of the
disc allows the use of a solid stainless steel seat.
The solid seat remains un-affected by high flow velocities and temperatures. A good
valve function is achieved even on difficult applications.
The SOMAS valves are delivered ready for installation and operation.
The valve assemblies are delivered factory tested as complete units with actuators,
positioners and accessories.
