HYDRAULIC QUARTER TURN
Servovalve quarter turn actuators are designed to operate ball,
butterfly , plug or any other valve with 90° rotation, for on-off or
modulating service.
Heavy duty design and special care on materials choice and accurate construction allow all Servovalve actuators to be suitable for installation in hostile and corrosive environmental.
Quarter turn actuators are available in both Rack-Pinion or Scotch Yoke execution as double or single acting design.
Rack-Pinion actuators are mainly adopted for small size valves or even
for big size valves but for extremely critical service and for accurate
modulating service, while Scotch Yoke execution is preferred for medium
and big size valves, due to their capacity of exalting output torques at
0° and 90° valve position.
To perform the best possible output
torque diagram relevant to the valve requested torque, Scotch Yoke is
available in symmetric or canted execution.
Output torque range is from 30 Nm up to 500.000 Nm
