Directional Spool Valve 4WEH32HD6X/OF6EG24N9EK4/B08P4,5 - Bosch Rexroth R901346222

When the main circuit supplies enough pressure for the pilot stage, internal supply saves a whole line. The 4WEH32HD6X/OF6EG24N9EK4/B08P4,5 works that way but takes the pilot oil return outside, switching 1100 l/min at 280 bar.

Benefits

• Internal pilot oil supply, external pilot oil return, one supply line is no longer needed.
• 1100 l/min flow at 280 bar maximum operating pressure.
• 35.4 kg weight, spool symbol D, two switching positions, four ports.
• Mounting pattern ISO 4401-10-09-0-05 for subplate mounting in size 32.
• 24 VDC through a 3-pole connector (2 + PE) to EN 175301-803, NBR seals, HL hydraulic fluid.

Applications

The typical use is a large axis whose system pressure reliably exceeds the pilot pressure. The external return keeps back pressure away from the pilot circuit and so steadies the switching times. Symbol D with two positions suits applications without a centre position.
