- HDE3 direct operated proportional directional valve, operating pressure to 350 bar and flows to 40 l/min;
- HDL3 direct operated, solenoid directional valves; flows to 80 l/min and operating pressures up to 350 bar;
- HDL5 direct operated, solenoid directional valves with operating pressures up to 320 bar and flow capacity to 120 l/min;
- HQE3 proportional flow control valves with pressure compensation, operating pressure to 250 bar and flow capacity up to 40 l/min;
- SDL | SDM | SDS sectional directional valves with operating pressures to 320 bar and flow to 60 l/min;
