Proportional Directional Valve 4WRZ32E1-520-7X/6EG24N9ETK4/D3M - Bosch Rexroth R900760544

Running a large axis from a simple manifold calls for a valve that provides its own pilot pressure. The 4WRZ32E1-520-7X/6EG24N9ETK4/D3M does that while carrying a 520 l/min nominal flow on the ISO 4401-10-09-0-05 interface.

Advantages

• Nominal flow of 520 l/min in size 32, up to 1600 l/min total flow.
• Internal pilot oil supply and internal return, the manifold carries four ports.
• Pressure reducing valve in the pilot stage, so pilot pressure does not follow system pressure.
• Weight of 42.8 kg, operating pressure up to 350 bar.
• Spool symbol E1, three switching positions, concealed manual override.
• NBR seals, HL hydraulic fluid, external amplifier electronics on 24 VDC.

Applications

It is used on main axes of large presses and on adjusting drives in plant engineering. Internal piloting shortens assembly and plumbing considerably. It requires permanently sufficient pressure at port P.
