NEW: linear valve actuator by STI S.r.l.

Pneumatic Valve Actuators

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