Proportional Directional Valve 4WRTE25W6-220L-4X/6EG24K31/A1V - Bosch Rexroth R901417696

When a control valve is replaced, mounting pattern and signal type decide how much work it is. The 4WRTE25W6-220L-4X/6EG24K31/A1V keeps the standard ISO 4401-08-08-0-05 pattern, takes its command as ±10 V and delivers 220 l/min nominal flow at 350 bar operating pressure.

Benefits

• The ISO 4401-08-08-0-05 pattern and 18.26 kg valve mass fit existing size 25 subplates.
• A ±10 V command value, fed straight from an analogue card, no converter needed.
• 220 l/min nominal flow and up to 870 l/min maximum flow.
• Internal pilot oil supply and internal pilot oil drain in the K31 version, no extra lines required.
• Spool symbol W6, FKM seals, 350 bar operating pressure, 24 VDC supply.

Application

Mainly aimed at modernisation work where the analogue control stays and only the hydraulics are renewed. Electrical spool position feedback improves control quality against older valves without feedback. Test rigs and presses are the typical locations.
