Proportional Directional Valve 4WRZ32E1-520-7X/6EG24N9K4/V - Bosch Rexroth R900960705

Large hydraulic systems usually provide pilot pressure centrally so that every valve responds alike. The 4WRZ32E1-520-7X/6EG24N9K4/V is built for that, fed through X and drained through Y, while metering 520 l/min nominal flow with spool symbol E1 at up to 350 bar.

Benefits

• 3 switching positions and 4 ports at 520 l/min nominal flow, spool symbol E1.
• Pilot oil comes from an external circuit and leaves through an external return, keeping pilot pressure separate from working pressure.
• No pressure reducing valve is fitted, the installation supplies the pilot pressure itself. Operating pressure up to 350 bar.
• Electrically the valve works with external electronics at 24 VDC, connected through a 7-pole connector (6 + PE) to EN 175201-804.
• Hole pattern ISO 4401-10-09-0-05 to ISO 4401, FKM seals for HL fluid, 1600 l/min maximum flow at 42.6 kg.

Applications

Its place is in press lines, rolling mills and test fields with a dedicated pilot pump. Because both pilot paths run outside, the pilot stage stays supplied even when the main circuit is unpressurised. The subplate has to carry the ISO 4401-10-09-0-05 pattern and route X and Y.
