Pilot Operated Control Valve


Series D30FP pilot operated control valve closes the gap between the direct operated D3FP valves and the conventional pilot operated D31FP valves. Providing high flow capacity and practically no flow limits like D31FP in the envelope size of the D3FP. The valve works with the hydraulic follower principle, with a moving sleeve as main spool.



  • Pilot operated with hydraulic follower sleeve
  • No flow limit up to 350 bar through the valve
  • Defined spool positioning at power down



  • High dynamics
  • High flow
  • Defined spool positioning in case of power supply breakdown
  • Onboard electronics
  • Closed loop position – controlled pilot valve and mainstage
