Large axes with a nominal flow of 600 l/min call for control rather than switching. This pilot-operated proportional directional valve in size 27 passes up to 1850 l/min at 270 bar and carries an integrated digital axis controller, so position control runs inside the valve instead of the plant controller.

Total price
At four digit flow rates, computing time decides how steady an axis runs. The 4WRLD27V600L-4X/MXY/24ED6T valve in size 27 carries an integrated digital axis controller, works at 600 l/min nominal flow and passes a maximum of 1850 l/min at 270 bar operating pressure.
Key benefits
- Integrated digital axis controller, the control loop is closed in the valve and not across the fieldbus
- 600 l/min nominal flow and 1850 l/min maximum, sized for large cylinders and press axes
- Analog command value +/-10 V, which connects to existing axis set point sources
- External pilot oil supply and external pilot oil return, independent of the pressure in the main circuit
- 270 bar operating pressure, mounting pattern ISO 4401-08-08-0-05, symbol V with 4 ports and 3 switching positions
- 24 VDC through a 12-pole connector (11 + PE), UKCA record for electromagnetic compatibility to SI2016/1091, weight 20.78 kg

Application
The valve controls main axes of large presses, forming lines and test plants that move several hundred litres per minute under control. The integrated axis controller relieves the plant control system and keeps the control loop short. External pilot oil supply has to be planned into the auxiliary circuit.
