Proportional Directional Valve 4WRZE10W6-85-7X/6EG24N9ETK31/A1V - Bosch Rexroth R900978823

Core pulls and ejectors on an injection mould need gentle ramps at limited flow. The 4WRZE10W6-85-7X/6EG24N9ETK31/A1V meters 85 l/min nominal flow for that job at operating pressures up to 315 bar and feeds its pilot stage from the working circuit, no extra lines needed.

Benefits

• 85 l/min nominal flow, maximum flow 170 l/min in size 10.
• Internal pilot oil supply and internal pilot oil return, a manifold free of X and Y drillings.
• Spool symbol W6 with 3 switching positions and 4 ports.
• FKM seals for HL hydraulic fluid, 8.76 kg weight.
• ±10 V command value on the on-board electronics, 24 VDC on a 7-pole (6 + PE) connector to EN 175201-804.

Applications

The valve drives mould movements on injection moulding and die casting machines as well as part removal axes. At 85 l/min acceleration and braking can be shaped through the command signal instead of letting the cylinder run into its end stops. FKM seals cope with permanently warm mould hydraulics.
