Proportional Directional Valve 4WRTE32E400P-4X/6EG24K31/A1M - Bosch Rexroth R900775781

A pilot-operated control loop in size 32 needs a spool that follows the command value under load. The 4WRTE32E400P-4X/6EG24K31/A1M uses internal spool position feedback and converts ±10 V into up to 400 l/min nominal flow.

Benefits

• Internal spool position feedback keeps the spool on target at up to 350 bar operating pressure.
• Linear characteristic curve with fine control range around the centre of spool symbol E, three switching positions across four ports.
• External pilot oil supply and external pilot oil return separate the pilot circuit from the working circuit of the manifold.
• 400 l/min nominal flow with flow up to 1600 l/min covers short rapid traverse phases as well.
• Connector, 7-pole (6 + PE) according to EN 175201-804 at 24 VDC, with NBR seals for HL hydraulic fluid.

Applications

The valve mounts on subplates and control manifolds with the ISO 4401-10-09-0-05 hole pattern, for example in presses, test benches and injection moulding machines with large cylinders. The fine control range suits force and position control, while flow up to 1600 l/min handles the fast strokes in between. External pilot oil supply and return keep pilot pressure available when working pressure drops for a while.
