Proportional Directional Valve 4WRZE25W6-220-7X/6EG24N9K31/A1D3V - Bosch Rexroth R900963714

When replacing a failed pilot-operated valve of the same size, the mounting pattern decides first. This valve sits on ISO 4401-08-08-0-05, delivers 220 l/min nominal flow with spool symbol W6 and accepts ±10 V as its command value.

Benefits

• Subplate mounting to ISO 4401-08-08-0-05, matching any standard size 25 subplate
• 220 l/min nominal flow, spool symbol W6
• External pilot circuit through X and Y, operating pressure up to 350 bar
• Command value ±10 V, 7-pole connector (6 + PE) to EN 175201-804
• FKM seals for HL hydraulic fluid, mass 20.6 kg

Application

A standard mounting pattern combined with a widespread voltage interface makes this valve a straightforward replacement in existing plant. Before swapping, match the spool symbol, the nominal flow and the pilot circuit arrangement. Both pilot ports have to be present on the subplate.
