Servo-hydraulics

The servo-hydraulic linear and torque amplifiers use advanced stepper motor technology for precise control of the spool within the valve enabling an accuracy measured in microns (µm) to be achieved.

Linear amplifiers - type: LVN,LVK & LVH
 
For linear applications requiring the highest accuracies three ranges are available dependant upon the flow requirements:
 
LVN (up to 80 litres/min at 160 bar);
 
LVK (up to 200 litres/min at 160 bar);
 
LVH (up to 320 litres/min at 300 bar).

Cylinders on all three ranges are available in diameters between 32-200mm, stroke lengths up to 1,200mm, stroke increments <0.008mm and accuracy's <0.03mm.

Torque amplifiers - type: SFM, SVN & SVK
 
Torque amplifiers are available with an output torque of up to 140Nm for the vane motors (SFM), 230Nm for the smaller piston motors (SVN) and 685Nm for the more powerful piston motors (SVK). A positional accuracy of <0.5° can be attained dependant upon the application.
