IMI STI is an international leader in valve actuation. We design and manufacture complete actuation systems, which can be fully customised to meet customer needs, to operate industrial valves for the most demanding applications and processes. We offer a diverse range of valve actuation products including linear and quarter turn actuators, smart and traditional positioners, and a full range of accessories.
PowerOur fast-stroking, highly-reliable actuators have been recognised for providing superior performance in severe service applications for over 50 years. Key applications include turbine bypass systems, steam damper heating, boiler level control (including nuclear); pump recirculation; emergency shut down, line isolation, and dampers for fans.
Oil & gasIn the oil & gas industries we provide compressor anti-surge (especially hot gas bypass), choke valves, gas to flare and dampers for fans.
LNGOver 90% of compressor anti-surge valves in LNG plants worldwide are fitted with IMI STI actuation control systems, maintaining plant up-time and operational efficiency.
Linear actuator (SC series) Our pneumatic valve piston actuators and damper actuators are purpose designed and manufactured for the operation of flow control devices such as dampers, louvers, butterfly and ball valves. They are ideal applications for power plants, refineries, pipe steel works and on board vessels.
Quarter turn actuator (RT series)Our RT Series offers a complete range of pneumatic and hydraulic quarter turn actuators suitable for all on-shore and off-shore applications, covering the general on-off valve and modulating control valve duties.
Control drive actuator (CM series)This pneumatic actuator system guarantees continuous operation in harsh environments; it is used in power stations, steel industries, petrochemical plants, desert areas, among others.
Positioners (PT series)We offer a wide range of positioners: pneumatic or electro-pneumatic, smart (very high flow rate) or 'traditional type'.
Accessories (AC series)A full range of accessories and control systems is available.
Fast delivery, with 24 hour spare parts shipment service, on site Field Service for spare parts installation and upgrade and regular maintenance of our actuator and accessories. Our spare parts service guarantees original equipment parts are interchangeable with existing ones. We provide training on site for better calibration and knowledge of our system and upgrade service.
