Proportional Directional Valve 4WRZE10W6-85-7X/6EG24N9TK31/A1V - Bosch Rexroth R900929342

On a cold start the main circuit is still sluggish, yet the pilot stage needs pressure straight away. The 4WRZE10W6-85-7X/6EG24N9TK31/A1V therefore draws pilot oil from an external circuit, drains internally and meters 85 l/min nominal flow at operating pressures up to 315 bar.

Benefits

• External pilot oil supply with internal pilot oil return, pilot pressure independent of the main circuit.
• 85 l/min nominal flow, maximum flow 170 l/min in size 10.
• Spool symbol W6, 3 switching positions and 4 ports, connection diagram ISO 4401-05-05-0-05.
• ±10 V command value, 24 VDC supply through a 7-pole (6 + PE) connector to EN 175201-804.
• FKM seals for HL hydraulic fluid, 8 kg weight.

Technical data

Applications

The valve suits outdoor installations, hydraulic steel structures and power units that stand idle for long periods. A small pilot pump provides control pressure while the main pump is still running up. The internal pilot drain saves the extra Y line in the manifold.
