Proportional Directional Valve 4WRTE10E1-100L-4X/6EG24EK31/F1V - Bosch Rexroth R901459805

A position control loop is easiest to tune when the valve characteristic stays linear over the entire range. The 4WRTE10E1-100L-4X/6EG24EK31/F1V offers exactly that curve shape at 100 l/min nominal flow, taking pilot oil internally and draining it through Y, at up to 350 bar.

Benefits

• 100 l/min nominal flow with spool symbol E1, 4 ports and 3 switching positions.
• Internal pilot oil supply with external drain through Y, so tank pressure does not act on the pilot stage.
• An internal position transducer reports spool position to the control loop, and the characteristic curve is linear. Operating pressure reaches 350 bar.
• The 4...20 mA command value feeds the on-board electronics directly, supplied with 24 VDC through a 7-pole connector (6 + PE) to EN 175201-804.
• Hole pattern ISO 4401-05-05-0-05 to ISO 4401, FKM seals for HL fluid, 170 l/min maximum flow at 8.47 kg.

Applications

The linear version is wanted in controlled axes with a superimposed position or force controller, for example on testing machines and simulation tables. The FKM seals allow higher oil temperatures in continuous duty. The current command stays stable over long cable runs.
