Product information for SOMAS exhaust valves

VSS ExhaustBelow are a few points illustrating what our exhaust valves really can do. Basic functionality as well as "bells and whistles" are adapted to each of our customers demand and based on our many years of experience.


  • Butterfly valve dimensions DN80 - DN500
  • Excentric ball segment valve dimensions DN25 - DN65
  • Pressure classes PN10 - PN25
  • Butterfly valves with metal seating and ball segment valves with HiCo-seat have excellent tightness to IEC 534-4 class V
  • backlash-free operation and accurate control between valve and actuator as well as between actuator and positioner
  • Easy maintenance since the seats in our butterfly and ball segment valves can be replaced without removing the actuator or any need for complete disassembly of the valve
