IMI STI

IMI STI provides total capability in valve actuation and positioning for severe service applications, drawing on more than 60 years of actuation expertise. The range includes linear, quarter-turn and stepper actuators, smart and traditional positioners, and instrumentation and accessories designed for demanding power, oil and gas, LNG and petrochemical duties.

Complete actuation packages combine actuators, positioners, accessories and diagnostics to deliver precise movement, simplified integration and reliable performance under demanding pressure, temperature and process conditions. Self-lubricating actuator designs reduce maintenance needs and support long-term reliability, while positioners provide accurate control, feedback and diagnostic capability. Applications include turbine bypass and steam systems requiring fast, repeatable response, anti-surge valve control, and a wide range of duties matched by actuator type, response speed, control behaviour and positioning accuracy to specific plant requirements.
