Proportional Directional Valve 4WRZE10W6-85-7X/6EG24N9EK31/A1D3V - Bosch Rexroth R900722664

At 85 l/min nominal flow this size 10 valve covers the upper performance range of the series. The external pilot return makes sure the pilot spool responds precisely even when the main circuit returns a large volume.

Benefits

• 85 l/min nominal flow for fast strokes, maximum flow up to 170 l/min
• External pilot oil return keeps the response stable at high return volume
• Internal pilot oil supply saves one pressure line inside the manifold
• Spool symbol W6 with 3 switching positions and 4 ports at 315 bar
• ±10 V command, on-board electronics, 24 VDC supply, weight 8.54 kg

Applications

Press drives, die cushions and fast lifting axes are the usual applications. With short cycle times and large return volumes the dedicated pilot return pays off. The valve is UKCA compliant to SI2016/1091.
