Linear Damper Actuator

SC is a complete line of linear double acting pneumatic actuators purposely designed and manufactured for the operation of flow control devices such as dampers, louvres, butterfly and ball valves. Thanks to their design, they are ideal for applications in power plants, refineries, pipe works and on board vessels.


  • Built in lubrication system makes it virtually maintenance free
  • Cylinder can be standard or special strokes
  • Double guide for piston and bushing
  • Excellent response times without need for boosters
  • Full stainless steel version available
  • Light and functional design allows easy installation
  • No dead volume is left in the actuator chamber in fully open or close position, minimising risk of overshoot
  • Suitable for harsh environments such as desert areas and petrochemicals plants
