Proportional Directional Valve 4WRZE10W8-85-7X/6EG24N9ETK31/A1M - Bosch Rexroth R900730929

Blow moulding machines cycle fast and leave little room in the manifold for extra lines. The 4WRZE10W8-85-7X/6EG24N9ETK31/A1M therefore routes pilot oil supply and return internally, regulates 85 l/min nominal flow through spool symbol W8 and accepts an analog ±10 V command value.

Benefits

• Internal pilot oil supply and internal return, no extra drillings in the manifold.
• Spool symbol W8 with 85 l/min nominal flow, maximum flow 170 l/min.
• Analog ±10 V command value on on-board electronics, 24 VDC supply.
• Version without pressure reducing valve, concealed auxiliary actuation fitted.
• Operating pressure up to 315 bar, size 10, weight 7.95 kg.

Applications

Blow moulding, thermoforming and deep drawing machines run many cycles per hour over short travels. Internal pilot routing keeps the manifold compact and the number of sealing points low. The size 10 subplate mounting keeps the valve interchangeable with other variants of the series.
