Servo Directional Valve 4WS2EM10-5X/90B11XHET315K31EV-100 - Bosch Rexroth R901535921

Position and force control loops need a valve that follows the command without detour. This directly actuated 4WS2EM servo directional valve in size 10 meters 90 l/min nominal, passes up to 180 l/min and works at operating pressures up to 350 bar.

Benefits

• Direct actuation without a pilot stage keeps the signal path in the control loop short.
• 90 l/min nominal and up to 180 l/min maximum flow at 350 bar.
• Internal pilot oil supply and internal return avoid additional pilot piping.
• CCC-Ex type examination certificate for plants that require this approval.
• 3.84 kg weight and an ISO 4401-05-05-0-05 pattern for subplate mounting.
• Driven by external electronics with a 30 mA/85 command, 24 VDC supply.

Applications

Typical uses are testing machines, rolling mill control, turbine control and simulators where position or force is corrected quickly. The electronics sit outside the valve and connect through a 7-pole (6 + PE) connector to EN 175201-804. FKM seals and HL hydraulic fluid are specified.
