Proportional Directional Valve 4WRLD16V200M-4X/MPT/24ND6T - Bosch Rexroth R901491924

A progressive characteristic settles the conflict between fine metering and short cycle time: at the start of the spool stroke the cross section changes slowly, after that quickly. The 4WRLD16V200M-4X/MPT/24ND6T uses exactly this spool symbol V and provides 250 l/min nominal flow, 800 l/min maximum, at 280 bar operating pressure.

Key benefits

• Progressive characteristic with a linear fine control range, fine metering at the start of the stroke and fast opening after it.
• 250 l/min nominal flow and 800 l/min peak at 280 bar operating pressure.
• Integrated digital axis controller with internal spool position feedback.
• Analog ±10 V command value over a 12-pole connector (11 + PE), 24 VDC supply.
• 3 switching positions and 4 ports, mounting pattern ISO 4401-07-07-0-05.
• NBR seals for HL hydraulic fluid, 12.48 kg valve mass.

Technical data

Applications

The characteristic suits axes that have to engage precisely and then travel briskly, such as die cushions, feed axes and handling systems. Internal pilot oil routing keeps the piping simple. UKCA conformity to EMC SI2016/1091 is in place.
