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 available 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 smooth operation and do not require any maintenance.
Standard SC actuators grant excellent response times without the use of booster; however, an high speed design is also available.
SC actuators are integrated by a wide range of positioners and accessories developed to meet the most adverse operating conditions. 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.

SC/V - Linear valve actuator

SC/V pneumatic linear piston actuators are designed to drive control valves for the most demanding applications of Power and Oil & Gas Industries, such as turbine bypass, stem conditioning valves, desuperheaters, valve compressors antisurge and many other.
Thanks to the special patented design of piston, including a double rings guiding system and a grease channel providing continuous lubrification, SC/V actuators grant smooth and precise valve operation without any maintenance for whole operating life. This series of actuators are designed with patented plug-in connection system for a wide range of customer-tailed accessories and control system to meet the most demanding and critical operating conditions of valves.
