Proportional Directional Valve 4WRDE10V50L-6X/MXT/24A5 - Bosch Rexroth R901487326

When a cylinder runs against a stop, main circuit pressure can briefly fall below pilot level. The 4WRDE10V50L-6X/MXT/24A5 therefore takes pilot oil from outside and stays controllable throughout, at 50 l/min nominal flow.

Benefits

• External pilot oil supply secures pilot pressure even when port P pressure drops.
• Internal pilot oil return saves the Y line compared with the fully external version.
• 50 l/min nominal flow, maximum flow 170 l/min, operating pressure 350 bar.
• Spool symbol V with a linear characteristic, 3 switching positions on 4 ports.
• 7.5 kg valve mass, NBR seals, mounting pattern ISO 4401-05-05-0-05, ±10 V command.

Applications

Intended for axes that frequently run against a mechanical stop or into pressure holding, for example clamping cylinders and small presses. External supply needs a dedicated pilot source, in exchange switching stays defined across the whole cycle. The return line should be lightly loaded because pilot oil is drained internally.
