Design Range

Torque Rating Range: From 40 to 1500 ft-lbs output torque

Features and Benefits

  • Greater process control with non-contacting absolute encoders that provide accurate position sensing
  • B.I.S.T., built-in self-test which never needs batteries to retain position data, even in the event of main power loss
  • Extreme environment performance made possible by non-intrusive design, 100% solid-state controls, and reliable digital communication control system
  • Versatility provided by flexible control configurations, setup and diagnostics in 11 languages, and advanced brush-less DC motor that supports most global voltages, AC or DC
  • 100% repeatable and redundant absolute encoder for position sensing
  • Electronic torque switch
  • 3-phase, 1-phase, and DC motors

Configurations

Non-intrusive, 100% solid-state, standard open-close applications

Non-intrusive, 100% solid-state, modulating to 1800 starts per hour to EN 15714, Class D - Continuous duty

Non-intrusive, 100% solid-state, network applications - Modbus, Foundation Fieldbus, HART, DeviceNet, Profibus DP w/ redundancy and Profibus PA

Training

Flowserve Limitorque offers practical product training at our global automation headquarters in Lynchburg, Va., and our state-of-the-art valve automation center in Houston. Taught by qualified instructors in classroom settings, these three-day courses emphasize hands-on training.
