Proportional Directional Valve 4WRZE10E50-7X/6EG24N9EK31/A1V - Bosch Rexroth R900968830

Clamping cylinders need little oil, yet they hold their state throughout the machining cycle. The 4WRZE10E50-7X/6EG24N9EK31/A1V meters 50 l/min nominal flow for that duty at operating pressures up to 315 bar, takes pilot oil internally and drains it through a separate external line.

Benefits

• 50 l/min nominal flow, maximum flow 170 l/min in size 10.
• Internal pilot oil supply with external pilot oil return, leaving the pilot stage relieved.
• Spool symbol E, 3 switching positions and 4 ports, connection diagram ISO 4401-05-05-0-05.
• FKM seals for HL hydraulic fluid, 7.97 kg weight.
• ±10 V command value, 24 VDC supply through a 7-pole (6 + PE) connector to EN 175201-804.

Technical data

Applications

The valve serves clamping hydraulics on machining centres, fixtures and workpiece supports. Its separate pilot drain keeps the pilot stage clear of pressure standing in the shared return. At 50 l/min closing and opening motion stays gentle enough for thin walled parts.
