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.
