Proportional Directional Valve 4WRZE32E520-7X/6EG24N9ETK31/A1M - Bosch Rexroth R901101490

Cycle time on an injection moulding machine is often won during closing and opening of the mould. The 4WRZE32E520-7X/6EG24N9ETK31/A1M moves the clamping unit with 520 l/min at 350 bar and takes its command as a ±10 V voltage.

Benefits

• 520 l/min nominal flow for short closing and opening times, the body carries up to 1600 l/min.
• ±10 V command straight from the machine control, electronics inside the valve, 24 V DC supply.
• Internal pilot oil supply and internal return, an extra control circuit is unnecessary.
• E spool with four ports and three switching positions, ISO 4401-10-09-0-05.
• 44.04 kg, NBR seals, HL hydraulic fluid, UKCA conformity.

Applications

Besides clamping units the valve controls ejector and core pull axes as well as presses with short cycles. Internal piston position feedback holds speed even under changing counter pressure. An operating pressure of 350 bar covers high clamping forces.
