Proportional Directional Valve 4WRTE32V400L-4X/6EG24K31/A1V - Bosch Rexroth R901190180

A size 32 valve does not always have to work at its upper limit. The 4WRTE32V400L is rated at 400 l/min nominal flow and uses the large body for low pressure drop, while permissible flow reaches 1600 l/min and operating pressure stands at 350 bar.

Key benefits

• 400 l/min nominal flow in a size 32 body, giving finer resolution of the characteristic curve than the 600 l/min version.
• 350 bar operating pressure and FKM seals for permanently warm circuits.
• Plus minus 10 V command value through a 7-pole connector to EN 175201-804.
• On-board electronics with internal spool position feedback, no separate amplifier needed.
• Spool symbol V, three switching positions, four ports, subplate mounting to ISO 4401-10-09-0-05.
• 37.24 kg, sized for size 32 manifolds and subplates.

Technical data

Applications

The type suits axes with medium oil demand that still hang on a large size 32 manifold, for instance in forming machines or lifting gear. Choosing 400 l/min instead of 600 l/min gains resolution in the controlled range, because the same spool travel distributes a smaller volume. External pilot oil supply with external return keeps pilot control separate from the main circuit.
