Servo Directional Valve 4WS2EM10-5X/45B11XHT315K31DV - Bosch Rexroth R901581929

The smaller the moving mass inside a valve, the faster it follows the command value. The direct actuated 4WS2EM10-5X/45 exploits that for dynamic control loops and handles 45 l/min nominal flow at up to 350 bar, with a CCC-Ex type examination certificate.

Benefits

• Direct actuated, no pilot stage and none of its delay.
• 45 l/min nominal flow, up to 90 l/min in size 10.
• CCC-Ex type examination certificate, documented conformity for the Chinese market.
• External pilot supply, internal pilot return, command value 30 mA/85 through external electronics.
• 350 bar operating pressure with FKM seals, hydraulic fluid HL.
• 3.8 kg weight, connection diagram ISO 4401-05-05-0-05.

Applications

The servo valve controls force, position or velocity in testing machines, simulators and mill cylinder adjustments. The amplifier electronics sit outside the valve and are sourced separately. The compact size 10 body keeps the moving mass low.
