Proportional Directional Valve 4WRTE25E1-220L-4X/6EG24EK31/A1M - Bosch Rexroth R900711074

Filters and coolers in the return line create back pressure that detunes the pilot stage of a valve. This version picks up pilot oil internally and drains it through a separate unpressurised line, at 220 l/min nominal flow and 350 bar.

Benefits

• External pilot oil return drains the pilot stage to tank without pressure, independent of filter and cooler.
• Internal pilot oil supply saves a separate pressure line to the pilot stage.
• 220 l/min nominal flow at 350 bar, flow up to 870 l/min in size 25.
• Spool symbol E1, 3 switching positions, ±10 V command value through the on-board electronics.
• 18.02 kg installed weight, NBR seals, connector 7-pole (6 + PE) to EN 175201-804.

Applications

Suitable for plants with a long return path or with return line filters, for example in paper and film machinery. It also keeps the pilot stage stable when several axes work in parallel on one shared tank. Connection diagram ISO 4401-08-08-0-05.
