The Eltorque hydraulic actuators consist of double-acting (HDQ) and single-acting (HSQ) types. They are designed to operate anywhere, even submerged or in hazardous areas. In emergency cases, all actuators can be operated by hand pump.

  • The torque range is from 120 – 20000 Nm.
  • Small size high torque.
  • Maximum operating pressure of 160 bar.
  • Precise and reliable operation.
  • Submerged upon request.
  • With mechanical emergency operation equipment.
