Proportional Directional Valve 4WRDE25V350L-6X/MXY/24A1 - Bosch Rexroth R901507461

A ±10 V voltage command is the standard interface of many axis controllers, and this 4WRDE25V350L-6X accepts it without a converter in between. The main stage is closed-loop controlled through internal position feedback and delivers 350 l/min nominal flow at up to 350 bar.

Key benefits

• Command value ±10 V straight into the on-board electronics, no extra converter needed.
• Nominal flow 350 l/min, flow up to 870 l/min.
• Internal spool position feedback for low hysteresis.
• Symbol V with a linear relation between command value and flow.
• Size 25, ISO 4401-08-08-0-05 interface, operating pressure up to 350 bar.
• CE conformity, NBR seals, 7-pole connector (6 + PE) to EN 175201-804.

Applications

This version is used in controlled axes of test rigs, presses and stage engineering when the outer loop already outputs ±10 V. Pilot oil is supplied and returned externally, so pilot pressure can be held independently of working pressure. Three switching positions and four ports cover the usual four-quadrant operation of a differential cylinder. The valve weighs 17.5 kg.
