Description

Two requirements meet in this variant, a spool carrying symbol W8 and an analogue command value of ±10 V. On that basis the 4WRKE25W8-350L-3X meters 350 l/min nominal flow at operating pressure up to 350 bar, taking pilot oil externally through X and draining it internally.

Benefits

Spool symbol W8 for controls that need a particular centre position
350 l/min nominal flow, flow rate up to 870 l/min
External pilot oil supply through X, internal pilot oil return
±10 V command value at on-board electronics, 24 V DC supply
17.92 kg weight, operating pressure up to 350 bar, NBR seals

Applications

The valve mounts on subplates to ISO 4401-08-08-0-05, for instance in press axes and forging manipulators. Inductive position feedback of the main spool holds the metering cross section steady when load pressure changes. HL hydraulic fluid is approved.

Manufacturer

Bosch Rexroth, material number R901049771. The type code 4WRKE25W8-350L-3X/6EG24TK31/A1D3M defines size, spool symbol, pilot oil routing and command value type without ambiguity.
