Efficiency. Durability. Quality.
Cameron’s MAXTORQUE™ gears feature patented AutoLock® technology that 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.

Efficiency. Durability. Quality.
Cameron’s MAXTORQUE™ gears feature patented AutoLock® technology that 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.

Features:

  •     Efficiencies 2 to 2.5 times commodity gears
  •     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-lb (1,355,818 Nm)

Benefits:

  •     Reduces work by up to 75%
    • Reduces turns, handwheel size and rim pull
    • Reduces stroke time
  •     Improves HSE profile

Target Applications:

  •     High-performance, metal-seated ball and butterfly valves
  •     Large butterfly valves
  •     High torque and/or high-thrust rising stem valves
  •     Marine and subsea with pressure compensation
  •     De-clutch and partial stroke
  •     River/sluice gates
  •     Remote/DC service (limited power availability)
  •     High cycle/high precision process control
  •     Extreme temperature environments Custom engineered solutions
