Proportional Directional Valve 4WRLD16V1-150L-4X/MPT/24ED6T - Bosch Rexroth R901520743

Cylinder axes that start slowly out of centre and only then switch to rapid travel need a pronounced fine control range. That is what the V1 spool of this pilot-operated 4WRLD valve in size 16 provides, metering 250 l/min nominal flow at 280 bar operating pressure.

Benefits

• Spool symbol V1 with a linear fine control range, giving smooth transitions when moving off centre.
• Nominal flow 250 l/min with up to 800 l/min possible through the valve.
• Integrated digital axis controller, so position control sits in the valve instead of a separate card.
• Operating pressure up to 280 bar on the ISO 4401-07-07-0-05 pattern at 11.58 kg.
• Internal pilot oil supply and internal return, no additional pilot circuit needed.
• NBR seals for HL hydraulic fluid, UKCA compliant to SI2016/1091.

Technical data

Applications

Typical duty covers feed and infeed axes on presses, welding lines and test equipment where short moves must be exact before large flows are released. Keeping the axis controller in the valve shortens the loop and limits wiring. Internal piloting assumes the main circuit stays under pressure.
