Servo Directional Valve 4WS2EM10-5X/30B11ET315K31EV/3 - Bosch Rexroth R901560830

The 4WS2EM10-5X/30B11ET315K31EV/3 servo directional valve is directly actuated, so the spool follows the 30 mA command current with no pilot stage in between. At 30 l/min nominal flow and a permissible 60 l/min the operating pressure reaches 315 bar.

Benefits

• Direct actuation of the spool, the 30 mA command current acts without a pilot stage.
• 30 l/min nominal flow with up to 60 l/min through the valve.
• Spool symbol V with 3 switching positions across 2 ports, ISO 4401-05-05-0-05 mounting pattern.
• Internal pilot oil supply and internal pilot oil return, no extra piping on the pilot side.
• External electronics on 24 VDC, 7-pole (6 + PE) connector to EN 175201-804.
• Operating pressure to 315 bar, FKM seals for HL hydraulic fluid, 3.9 kg weight.

Application

Servo valves of this design control position, force and speed on test rigs, simulators and materials testing machines where the axis has to track the command closely. An external servo amplifier in the cabinet drives the valve. The fine control edges make the specified oil cleanliness a condition of reliable operation.
