Proportional Directional Valve 4WRZE10W8-85-7X/6EG24N9EK31/A1V - Bosch Rexroth R900935674

In blow moulding every tenth of a second costs cycle time, while a hard touchdown of the mould costs tooling. The 4WRZE10W8-85-7X/6EG24N9EK31/A1V answers both at 85 l/min rated flow and 315 bar maximum, with a blocked centre that holds the mould.

Benefits

• 85 l/min rated flow for short closing times, flow up to 170 l/min.
• Spool symbol W8 blocks at centre and holds the mould without actuation.
• Internal pilot oil supply with external pilot oil return, without a pressure reducing valve.
• Command value 10 V bipolar, 24 VDC supply, operating limit 315 bar.
• Concealed manual override, 8.66 kg, size 10, FKM seals for HL fluid.

Application

Clamping units, blow pin and calibration axes on blow and injection moulding machines use this valve. A stepped command ramp lets the mould close quickly and touch down slowly. For smaller machines, 25 and 50 l/min are available.
