Servo Directional Valve 4WS2EM10-5X/30B11XHET315K31EV-100 - Bosch Rexroth R901215886

Not every test axis manages on 10 l/min, yet 45 l/min is often already too coarse. The 4WS2EM10-5X/30B11XHET315K31EV-100 sets its curve at 30 l/min, covering the middle of size 10 at operating pressures up to 350 bar.

Benefits

• 30 l/min nominal flow as the middle stage, with a maximum flow of 60 l/min.
• Explosion protection to 2014/34/EU, equipment group II 1G, together with CCC-Ex conformity.
• Direct actuation with internal pilot oil supply plus internal return, no extra pilot line needed.
• Analog command value 30 mA/85 from external electronics, 24 VDC supply, 4 switching positions across 2 ports.
• 3.9 kg weight, FKM seals, subplate mounting to ISO 4401-05-05-0-05.

Application

This stage suits fatigue testing machines, closed loop drives as well as mid size positioning axes in hazardous areas. The internal pilot circuit simplifies fitting into existing manifolds. Controller design follows the valve curve together with the cylinder bore.
