Down hole safety valves are a mission-critical application. Current valves are driven by hydraulics that threaten pollution when the hydraulic lines are ruptured. A non-hydraulic valve is needed.


We designed and built from scratch a linear magnetic motor to drive the valve open and a magnetic, low power hold open to ensure fail safe operation.


Initial feasibility study was six months. First prototype was built within three months after go-ahead. Full-sized prototype took less than nine months from design to completion.
