Servo Directional Valve 4WS2EM6-2X/15B11ET315K17EV/3 - Bosch Rexroth R901560831

Servo valves earn their place where an axis has to follow a rapidly changing command profile. The 4WS2EM6-2X releases 15 l/min nominal flow, copes with up to 28 l/min maximum flow and works at up to 315 bar operating pressure. Pilot oil supply and return run internally, while external electronics close the loop using a 30 mA/85 current command.

Benefits

• 15 l/min nominal flow at 28 l/min maximum flow, operating pressure up to 315 bar
• Direct actuation in size 6, hole pattern ISO 4401-03-02-0-05
• Internal pilot oil supply and internal pilot oil return, no extra control oil piping
• Spool symbol V with three switching positions and two ports
• Driven by external electronics with a 30 mA/85 current command, 24 VDC supply
• Only 1.12 kg unit weight, FKM seals for HL hydraulic fluid

Application

Typical duties are force and position control on materials testing machines, simulators and research rigs where frequency response and resolution matter more than flow. The low mass allows mounting close to the cylinder, which keeps the oil column between valve and actuator short. Amplifier electronics are not part of the delivery and are selected separately.

Manufacturer

Bosch Rexroth lists this servo valve under material number R901560831.
