Proportional Directional Valve 4WRDE10W6-50P-6X/MPT/24A5 - Bosch Rexroth R901507908

An axis that creeps through most of its cycle and only needs volume on the return stroke turns nervous behind an oversized valve. The 4WRDE10W6-50P-6X/MPT/24A5 therefore carries a 50 l/min nominal rating in size 10 while keeping up to 170 l/min available, all under a ±10 V command value.

Benefits

• 50 l/min nominal flow keeps resolution in the working range, while up to 170 l/min stays free for fast moves.
• A ±10 V command value works with any common analogue output card, no converter required.
• On-board electronics inside the valve, 24 VDC supply through a 7-pole connector (6 + PE) to EN 175201-804.
• Spool symbol W6, three switching positions, four ports, ISO 4401-05-05-0-05 mounting pattern.
• 350 bar operating pressure at 7.5 kg valve mass, NBR seals for HL hydraulic fluid.

Application

Typical places are feed and clamping axes on machine tools and test rigs with changing load. The ±10 V command suits existing analogue controllers and amplifier cards. At 7.5 kg the valve stays manageable for size 10.

Manufacturer

Bosch Rexroth lists this valve under material number R901507908. NBR seals and the release for HL hydraulic fluid are set at the factory.
