Proportional Directional Valve 4WRLD16V250L-4X/MXY/24SD6T - Bosch Rexroth R901518407

Position-controlled cylinder and motor axes in presses, test rigs and forming machines need a flow that follows the command value without a separate amplifier. The 4WRLD16V250L-4X/MXY/24SD6T handles a nominal flow of 250 l/min at up to 350 bar and closes the loop on spool position inside the valve.

Benefits

• Nominal flow 250 l/min with 800 l/min maximum flow, so fast traverse strokes stay within one valve size.
• Operating pressure up to 350 bar covers the upper end of the size 16 range.
• Digital axis controller built in, analog command value plus/minus 10 V, no external control card required.
• Three switching positions with internal spool position feedback for repeatable metering.
• External pilot oil supply and external pilot oil return keep pilot pressure independent of the main circuit.
• Mounting pattern ISO 4401-07-07-0-05 in size 16 fits existing subplates.

Applications

Typical duties are position and velocity controlled axes in presses, test benches and forming equipment calling for 250 l/min at 350 bar. NBR seals match hydraulic fluid HL. External pilot supply suits plants that already run a dedicated pilot circuit at stable pressure. The 12-pole connector to EN 175201-804 links the valve to the machine control.
