Servo Directional Valve 4WS2EM10-5X/10B11XHET315K31EV-102 - Bosch Rexroth R901268101

Once oil temperature stays high, standard seals age far faster than FKM does. The 4WS2EM10-5X/10B11XHET315K31EV-102 is sealed with FKM while metering a finely resolved 10 l/min nominal flow.

Benefits

• FKM seals tolerate higher continuous temperatures than standard materials.
• 10 l/min nominal flow for fine force plus position control, maximum flow 19 l/min.
• Direct actuation with internal pilot oil supply plus internal return, 4 switching positions across 2 ports.
• Analog command value 30 mA/85 from external electronics, 24 VDC supply, 7-pole connector (6 + PE).
• 3.86 kg weight, ISO 4401-05-05-0-05 interface, CCC-Ex conformity with a type examination certificate.

Application

Endurance test rigs, hot forming lines as well as plants with long duty cycles keep tank temperature high, which is where this build belongs. The low nominal flow keeps the axis stable even on small cylinder bores. Amplifier electronics are ordered separately.
