Overview

Cameron MAXTORQUE high-performance valve products include gears that feature patented AutoLock® technology, which allows for high-performance worm gear solutions with the self-locking characteristics of conventional gearboxes. This means up to a 75% reduction in the workload required to operate a valve, leading to an improved HSE profile and worker efficiency on manual valves and smaller actuators on motorized valves.
