Proportional Directional Valve 4WRDE25V350L-6X/MXYWG/24A1 - Bosch Rexroth R901539232

When a PLC drives its hydraulic axes with a plus or minus 10 V analogue output, the 4WRDE25V350L-6X/MXYWG/24A1 connects without any signal converter. The size 25 valve controls 350 l/min nominal flow, withstands 350 bar operating pressure, and releases up to 870 l/min at peak while the cylinder runs in rapid traverse.

Key benefits

• Voltage interface of plus or minus 10 V, the common range of any analogue output card, so no converter is needed.
• Internal piston position feedback keeps the spool stable under load changes up to 350 bar.
• Peak flow of 870 l/min against 350 l/min nominal leaves reserve for fast return strokes.
• Connector, 7-pole to EN 175201-804, a standard cable assembly rather than a special harness.
• ISO 4401-08-08-0-05 interface makes the valve interchangeable against any product on the same hole pattern.

Technical data

Applications

Valves of this class run in injection moulding machines, hydraulic presses and stamping lines where one axis controls force plus position at the same time. HL hydraulic fluid together with NBR seals covers ordinary mineral oil operation. The valve weighs 17.5 kg, external pilot oil supply plus external pilot oil return.

Manufacturer

Manufactured by Bosch Rexroth as type 4WRDE25V350L-6X/MXYWG/24A1, material number R901539232. Only the material number is binding for spare part stock, because the current-signal sibling carries an almost identical type code.
