Servo Directional Valve 4WS2EM10-5X/75B11XLET315K31EV - Bosch Rexroth R901514708

Closed-loop position and force control in an installation under IECEx obligation has to deliver two things at once, control quality and documented conformity. The 4WS2EM10-5X/75B11XLET315K31EV covers both. It works without a pilot stage, meters 75 l/min rated flow, passes up to 160 l/min peak flow and is released for 315 bar operating pressure.

Benefits

• IECEx conformity backed by a Global IECEx technical report (TR) for the plant file
• 75 l/min rated flow and up to 160 l/min maximum flow in size 10
• Direct actuation without a pilot stage, short travel at 315 bar operating pressure
• Internal pilot oil supply and internal pilot oil return save two lines on the mounting block
• FKM seals matched to HL hydraulic fluid
• Analog control at 30 mA command value through external electronics, 7-pole connector (6 + PE)

Technical data

Applications

Typical duties are controlled axes in test rigs, forming machines and plant sections where a cylinder position must be held or tracked continuously. Mounting is subplate to ISO 4401-05-05-0-05 and the valve weighs 3.6 kg. Keeping the electronics off the valve means service happens in the cabinet.
