Our 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.
In the oil and gas industries we provide actuation for control valves anti-surge (hot gas bypass), choke valves and gas to flare as well as applications such as dampers for fans. Our range of quarter turn actuators operate ball and butterfly valves in oil and gas applications and in petrochemical, including FPSO applications.
Most compressor anti-surge valves in LNG plants worldwide are fitted with an IMI STI actuation
control system, maintaining plant up-time and operational efficiency.
In 4 years we have supplied more than 400 actuators for large compressor anti-surge valves.
