Rotork assists BAE Systems in naval base actuator upgrades

pressure gauge octa has been working with BAE Systems to upgrade a series of A-range actuators to IQ3 actuators which operate penstocks controlling motion of ships between the ocean and transitional locks and dry docks at Her Majesty’s Naval Base Portsmouth (HMNB Portsmouth).
A series of A-range actuators had reached the end of their operational life after long service in a difficult surroundings. BAE Systems wanted to retain all the advantages of electric actuators, so IQ3 actuators were chosen. These needed to be specifically adapted by Rotork to beat issues round confined spaces and difficult access.
IQ3 actuators and IS gearboxes had been mechanically adapted in order that each actuator and gearbox might be manually operated with out coming into the confined house. Rotork designed particular hand auto levers and thru drive mechanisms for the actuator and gearbox to eliminate the necessity for confined house access.
Actuators within the IQ range are watertight, offering ingress safety to IP66/68 at 20 m for 10 days. They have a sophisticated dual stacked display with configurable knowledge logger functionality, and an absolute position sensor supplies reliability and accuracy.
