Proportional Directional Valve 4WRPDH6CB25P-2X/M/24ND6T - Bosch Rexroth R901448362

Positioning and clamping axes are sized by the nominal flow their cylinder needs per second of travel. The direct actuated 4WRPDH6CB25P-2X/M/24ND6T supplies 25 l/min at size 6 and controls it through internal spool position feedback at up to 350 bar.

Benefits

• 25 l/min nominal flow - flow up to 41 l/min, weight 3.56 kg at size 6.
• Spool symbol C across 4 switching positions - internal spool position feedback for a linear characteristic with a marked fine control range.
• Direct actuation - the valve runs without pilot oil from the hydraulic system.
• One command input for ±10 VDC or 4 to 20 mA - 24 VDC supply, 12-pole connector (11 + PE).
• Maximum operating pressure 350 bar - subplate mounting ISO 4401-03-02-0-05, NBR seals for HL hydraulic fluid, UKCA conformity.

Applications

The valve is used on positioning and feed axes of special purpose machinery, in clamping circuits and for controlled lifting motion on test setups. Besides command value and supply, the 12-pole connector (11 + PE) also carries the diagnostic signals. With flow reaching 41 l/min there is headroom above the 25 l/min nominal rating.
