Directional Spool Valve 4WEH32L6X/6EG24N9ES2K4/10B10 - Bosch Rexroth R901231199

Back pressure in the return lengthens the switching time of a pilot stage. The 4WEH32L6X/6EG24N9ES2K4/10B10 avoids that with an external pilot drain and internal pilot supply, switching up to 1100 l/min at 280 bar in size 32.

Benefits

• Pilot oil supplied internally, drained externally, the pilot drain stays clear of back pressure in the main return.
• 1100 l/min flow at 280 bar maximum operating pressure on the ISO 4401-10-09-0-05 pattern.
• Spool symbol L with three switching positions across four ports in size 32.
• 38.16 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.

Applications

The valve is intended for control manifolds where several large valves relieve into the tank together. The separately routed pilot drain keeps switching times steady even while other axes switch at the same time. How the ports connect in mid position follows from spool symbol L.
