Proportional Directional Valve 4WRLE25W350SJ-4X/MXY/24A1 - Bosch Rexroth R901404876

Not every axis tolerates a linear opening, and many run more smoothly when the valve opens cautiously at low command values. The 4WRLE25W350SJ-4X/MXY/24A1 uses spool symbol W with a progressive characteristic for that, at 350 l/min nominal flow.

Benefits

• Spool symbol W in the progressive SJ version, for fine metering in the lower part of the command curve.
• 1250 l/min maximum flow leaves generous headroom above the 350 l/min nominal rating.
• External pilot oil supply and external pilot oil return separate the pilot circuit from the main circuit.
• Operating pressure up to 350 bar, 3 switching positions on 4 ports, CE conformity.
• 18.58 kg valve mass, mounting pattern ISO 4401-08-08-0-05, ±10 V command at 24 VDC.

Applications

Intended for plants where a heavy slide or table has to start without a jolt, for example on forming and testing machines. A fully external pilot circuit suits power units with their own pilot supply. The progressive curve calls for a controller that accounts for the non-linear relation between command and flow.
