Proportional Directional Valve 4WRDE25V350L-6X/MPYWG/24A1 - Bosch Rexroth R901568350

Between size 25 and size 32 lie several centimetres of manifold height and roughly 25 kg of weight. The 4WRDE25V350L-6X/MPYWG/24A1 draws a nominal flow of 350 l/min at 350 bar operating pressure from the smaller frame size while weighing 17.5 kg.

Key benefits

• 350 l/min at 17.5 kg - high power density in size 25, with up to 870 l/min possible by valve size.
• Internal spool position feedback - a linear characteristic and a repeatable flow command.
• Command value ±10 V on 24 VDC - on-board electronics wired through a 7-pole connector (6 + PE) to EN 175201-804.
• Internal pilot supply with external drain - only the Y line has to be added.
• Interface ISO 4401-08-08-0-05 - size 25 subplate mounting, 4 ports, 3 switching positions.
• NBR seals, hydraulic fluid HL - spool symbol V, pilot-operated spool valve.

Technical data

Applications

The valve pays off wherever a manifold has to stay compact while the axis still needs a lot of oil, for example in machine tools, test rigs and medium sized presses. Compared with a size 32 valve it saves noticeable weight and space. Because pilot oil is taken internally, the main circuit has to carry pressure.
