Servo Directional Valve 4WS2EM10-5X/45B11XHET210K31EV - Bosch Rexroth R901262085

Building a servo axis without separate X and Y lines saves piping and failure points. The 4WS2EM10-5X/45B11XHET210K31EV feeds and drains its pilot stage internally while controlling 45 l/min nominal flow at 350 bar.

Benefits

• Internal pilot oil supply and internal pilot oil return, so the subplate needs no extra control lines.
• 45 l/min nominal flow, 90 l/min maximum, enough for dynamic test cycles.
• 350 bar operating pressure with direct actuation, three switching positions and two ports.
• CCC-Ex conformity backed by an Ex TR type examination certificate.
• 3.84 kg weight with FKM seals for HL hydraulic fluid.

Application

The valve drives servo cylinders in testing machines, fatigue rigs and forming equipment with changing load profiles. A 90 l/min peak covers short fast strokes without oversizing the nominal stage. Internal pilot routing shortens assembly time when retrofitting existing manifolds.
