Servo Directional Valve 4WS2EM10-5X/60B11XHET315K31EV-100 - Bosch Rexroth R901535926

In dynamic control loops the response time of the valve decides the quality of the axis. The direct actuated servo directional valve 4WS2EM10-5X/60B11XHET315K31EV-100 in size 10 provides 60 l/min nominal flow, 130 l/min maximum, and withstands 350 bar operating pressure. Pilot oil is supplied and returned internally, while the control electronics sit outside the valve.

Key benefits

• 60 l/min nominal flow and 130 l/min peak, metered through the analog 30 mA current command value.
• Direct actuated, which keeps response times short without an upstream pilot stage.
• Operating pressure up to 350 bar, FKM seals for HL hydraulic fluid.
• 4 switching positions and 2 ports, mounting pattern ISO 4401-05-05-0-05.
• 24 VDC supply through a 7-pole connector (6 + PE) to EN 175201-804.
• Only 3.84 kg valve mass, mounts on standard size 10 subplates.

Applications

The valve serves position and force control loops on testing machines, simulators and machine tools. The CCC-Ex type examination certificate documents the Chinese approval for explosion-protected applications. The matching control electronics are ordered separately and installed in the control cabinet.
