High Performance Worm Gear

Cameron MAXTORQUE* high-performance valve products feature patented AutoLock® technology that allows for high-performance worm gear solutions with the self-locking characteristics of conventional gearboxes. This means less work is required to actuate valves, leading to an improved HSE profile and worker efficiency on manual valves and smaller actuators on motorized valves.

  • Self-locking design
  • Double-enveloping gear set
  • Unique tooth form to reduce microscopic stresses
  • Superior sealing system
  • Capable of handling torques in excess of 1,000,000 ft lbf [1,355,818 Nm]
