For control tasks where the opening cross section has to follow the command value even under changing load: this direct operated proportional directional valve senses the spool position internally and corrects it. It meters 50 l/min at up to 315 bar and weighs 6.48 kg.

Total price
The spool of this direct operated proportional directional valve of the 4WRPDH series is measured by an internal position transducer and corrected continuously. The relation between command value and opening cross section therefore holds under fluctuating load, at 50 l/min nominal flow and a maximum operating pressure of 315 bar.
Benefits
- Internal spool position feedback keeps the characteristic between command value and opening defined across all 4 switching positions
- Command value either ±10 VDC or 4 ... 20 mA, supply 24 VDC, evaluated by the on-board electronics
- Direct actuation without a pilot stage, so no separate pilot oil circuit is needed, 50 l/min nominal flow at 6.48 kg weight
- Spool symbol C3 with 4 ports on mounting pattern ISO 4401-05-04-0-05 for subplate mounting
- NBR seals for HL hydraulic fluid at a maximum operating pressure of 315 bar

Applications
The valve belongs on axes that have to hold a position or a force, for example on test machines, forming presses and motion simulators. Spool position feedback reduces the effect of flow forces on the opening, which makes closed loop control easier to tune. Conformity is declared as UKCA with electromagnetic compatibility to SI2016/1091.
