Proportional Directional Valve 4WRZ32W8-520-7X/6EG24N9TK4/V - Bosch Rexroth R901224358

A cylinder with a large bore needs oil in quantities that only size 32 provides. The 4WRZ32W8-520-7X/6EG24N9TK4/V carries 520 l/min nominal flow at up to 350 bar and takes pilot oil externally through the X port, while the pilot return runs internally.

Benefits

• Spool symbol W8 with 3 switching positions and 520 l/min nominal flow in size 32.
• Pilot oil arrives externally through the X port and returns internally.
• No pressure reducing valve is fitted, the installation supplies the pilot pressure itself. Operating pressure up to 350 bar.
• Control is handled by external amplifier electronics, and the valve is powered with 24 VDC through a 7-pole connector (6 + PE) to EN 175201-804.
• Mounting pattern ISO 4401-10-09-0-05, FKM seals for HL fluid, maximum flow 1600 l/min, weight 43.9 kg.

Applications

It is used in forming presses, rolling mill hydraulics and large test rigs with their own pilot supply. External supply keeps the pilot stage working through unloading phases as well. At 43.9 kg and with the ISO 4401-10-09-0-05 hole pattern the valve belongs on a correspondingly sized subplate.
