Proportional Directional Valve 4WRZE25E220-7X/6EG24TK31/A1M - Bosch Rexroth R901171561

When existing plants are rebuilt a pilot pressure line is usually there, while a dedicated drain bore rarely is. This version adapts to that and transfers 220 l/min nominal flow at 350 bar.

Benefits

• External pilot oil supply with internal return, the existing manifold stays unchanged.
• 220 l/min nominal flow at 350 bar, flow up to 870 l/min.
• ±10 V command value, wired straight to existing analog cards.
• Spool symbol E, 3 switching positions, internal spool position feedback.
• 20.58 kg installed weight, UKCA declaration, NBR seals.

Applications

Intended for modernising presses, calenders and lifting plants with existing pipework. Pilot pressure comes from the existing X line and pilot oil returns together with the main flow. Connection diagram ISO 4401-08-08-0-05.
