Proportional Directional Valve 4WRZ32W8-520-7X/6EG24N9ETK4/V - Bosch Rexroth R900741610

On a size 32 manifold two additional pilot lines are a noticeable assembly effort. The 4WRZ32W8-520-7X/6EG24N9ETK4/V avoids them because pilot supply and return run internally, metering 520 l/min nominal flow with spool symbol W8 at up to 350 bar.

Benefits

• 520 l/min nominal flow with spool symbol W8, 4 ports and 3 switching positions.
• Pilot oil supply and return both run inside the valve, which saves two external control lines.
• This version carries no pressure reducing valve in the pilot stage, operating pressure reaches 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 43.58 kg.

Applications

The layout suits presses and power units whose working pressure stays permanently above the pilot pressure required and whose return remains pressure free. The subplate then only needs the ISO 4401-10-09-0-05 hole pattern. The FKM seals allow operation at elevated oil temperature.
