In fast control loops the dynamics of the valve matter more than its size. This directly actuated size 10 servo valve handles 90 l/min nominal at 350 bar, weighs 3.84 kg and holds a CCC-Ex type examination certificate. Pilot oil is supplied and returned internally, so no extra pilot lines are needed.

Position and force control loops need a valve that follows the command without detour. This directly actuated 4WS2EM servo directional valve in size 10 meters 90 l/min nominal, passes up to 180 l/min and works at operating pressures up to 350 bar.
Benefits
- Direct actuation without a pilot stage keeps the signal path in the control loop short.
- 90 l/min nominal and up to 180 l/min maximum flow at 350 bar.
- Internal pilot oil supply and internal return avoid additional pilot piping.
- CCC-Ex type examination certificate for plants that require this approval.
- 3.84 kg weight and an ISO 4401-05-05-0-05 pattern for subplate mounting.
- Driven by external electronics with a 30 mA/85 command, 24 VDC supply.
