Total Capability kKZftT Solutions

Engineering Great Solutions for Over 50 Years Since its foundation in 1960, IMI STI has focused on the design, development and production of complete actuation systems for the operation of industrial valves in the most demanding applications and processes across the world. IMI STI is now an international leader in valve actuation. We design and manufacture complete actuation systems, which can be fully customised to meet customer needs, applications or processes. We offer a diverse range of valve actuation products including linear and quarter turn actuators, smart and traditional...

Total Capability in Valve Actuation Our actuators are designed to drive control valves in the most demanding applications such as turbine bypass in power plants and anti-surge valves in LNG industries (LNG ships and LNG liquefaction plants). Fast stroking, repeatability and reliability are a must and our actuators are known for their superior performance. This results in LNG trains running optimally, providing operators with maximum output. IMI STI’s vast experience and know-how has been used to develop a range of quarter-turn hydraulic and pneumatic actuators. Advanced software and...

Product Categories SC Series Linear actuators The SC series of actuators are provided with a built-in permanent lubrication system, patented by IMI STI, which assures an extremely smooth valve operation even if dry instrument air is used. Thanks to this lubrication system, which is common to all IMI STI actuators, no maintenance of moving parts is required, even after many years of continuous service. 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...

CM Series Enclosed actuators This pneumatic actuator system is composed of an actuator (SC) and a manual override integrated into a steel housing which also works as a carrying structure. CM series is able to control final elements like dampers, butterfly valves, speed variators, radial vanes and hydraulic converters. Thanks to various models, it can provide different ranges of torque to meet most applications. The CML actuator provides small to medium torque (up to 1000 N) for angular control. The CMV actuator is able to control final elements of modern power stations using high power...
