Large press cylinders call for high flow and still a fine metering range. The 4WRTE25E350P moves 350 l/min nominal flow at 350 bar, peaks at 870 l/min and carries FKM seals for hot or demanding fluids. Mass 18 kg.

Once a press cylinder has to be filled within seconds, maximum flow decides the cycle time. The 4WRTE25E350P-4X/6EG24ETK31/A1V delivers 350 l/min nominal flow and passes up to 870 l/min at peak, at 350 bar operating pressure.
Benefits
- 870 l/min maximum flow alongside 350 l/min nominal flow leaves headroom for rapid traverse.
- FKM seals instead of NBR widen use to higher oil temperatures and demanding hydraulic fluids.
- Spool symbol E provides a fine metering range around centre, so smooth start-up survives the large nominal size.
- Internal pilot oil supply with external pilot oil return keeps surges in the tank line away from the pilot circuit.
- Mounting pattern ISO 4401-08-08-0-05 in size 25, valve mass 18 kg, ±10 V command at 24 VDC.

Applications
Presses, forging plant and large test rigs where a cylinder travels under high load in closed loop. The FKM version suits installations running at sustained high oil temperature. On-board electronics accept the command value straight from the machine controller, so no amplifier card is needed in the cabinet.
