Directional Spool Valve 4WEH32HR6X/6EG24N9TSK4/B08 - Bosch Rexroth R901030559

An external pilot supply with an internal return is the compromise between secured switching pressure and low piping effort. The 4WEH32HR6X/6EG24N9TSK4/B08 uses it in size 32 at up to 1100 l/min and 280 bar maximum operating pressure.

Benefits

• Pilot oil supplied externally, drained internally, secured pilot pressure without a return line of its own.
• 1100 l/min flow at 280 bar maximum operating pressure on the ISO 4401-10-09-0-05 pattern.
• Spool symbol R with three switching positions across four ports in size 32.
• 39.77 kg weight, NBR seals for HL hydraulic fluid.
• 24 VDC through a 3-pole (2 + PE) plug to EN 175301-803, solenoid actuation of the pilot stage.

Technical data

Applications

It is applied on main axes of large presses and lifting gear whose power unit runs a pilot pressure circuit of its own. Because the pilot drain is internal, one line per valve in the manifold is saved. Where the tank path carries back pressure, the version with an external drain is the correct one.
