Proportional Directional Valve 4WRPDH10C3B50L-2X/M/24SD6T - Bosch Rexroth R901498902

Without feedback of spool position a proportional valve drifts with temperature and load. The 4WRPDH10C3B50L-2X/M/24SD6T measures that position internally and keeps the relation between command value and flow stable, at 50 l/min nominal flow and up to 315 bar.

Benefits

• Internal spool position feedback, which keeps hysteresis low and positions reproducible.
• Spool symbol C3 with four switching positions, nominal flow 50 l/min.
• Operating pressure up to 315 bar on the ISO 4401-05-04-0-05 mounting pattern.
• Direct actuated, usable without pilot oil and without a minimum pressure.
• On-board electronics for ±10 VDC or 4 ... 20 mA, 24 VDC supply.
• 12-pole connector (11 + PE), NBR seals, mass 7.28 kg.

Applications

Typical duties are positioning and metering tasks on test rigs, assembly lines and machine tools. Internal feedback keeps the characteristic curve reproducible even as oil temperature changes. Closed-loop position control of the axis additionally needs a measuring system on the cylinder.
