Proportional Directional Valve 4WRTE10V100P-4X/6EG24ETK31/F1M - Bosch Rexroth R901188972

A manifold without pilot ports and a controller with current outputs, that is the starting point for this valve. The 4WRTE10V100P-4X/6EG24ETK31/F1M is piloted internally, takes 4...20 mA as its command and meters 100 l/min nominal flow with internal spool feedback up to 350 bar.

Benefits

• 3 switching positions and 4 ports at 100 l/min nominal flow, spool symbol V.
• Pilot oil is taken internally and returned internally, so no separate X and Y line is needed.
• An internal position transducer reports spool position to the control loop, and the characteristic curve is linear with a pronounced fine control range. 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, NBR seals for HL fluid, 170 l/min maximum flow at 8.41 kg.

Applications

Valves like this sit in press feed axes, in lifting gear and in hydraulic test equipment with long signal paths. The fine control range improves resolution at small commands without capping the rapid stroke. At 8.41 kg the valve is easy to handle single handed.
