SC - Linear damper actuator
SC is a complete line of linear pneumatic actuators purposely designed and manufactured for the operation of flow control devices such as dampers, louvers, butterfly and ball valves. Thanks to their design, they find ideal application in power plants, refineries, pipe steel works and on board of vessels.
The range of products includes double acting units and are ***ailable in different sizes.
The use of a built-in permanent lubrication system, patented by STI and common to all the range of STI actuators, assures an extremely ***ooth operation and do not require any maintenance.
Standard SC actuators grant excellent resp***e times without the use of booster; however, an high speed design is also ***ailable.
SC actuators are integrated by a wide range of positioners and accessories developed to meet the most adverse operating conditi***. They can be provided with gearbox for the manual operation in case of emergency. Various linkages for the coupling to the control devices can be designed according to the customers’ specific requirements.
