Directional Spool Valve 4WEH32T6X/6EG24N9ES2K4/B10P4,5 - Bosch Rexroth R901066177

Internal pilot supply saves one line at the manifold, external drain keeps back pressure at the pilot stage low. The 4WEH32T6X/6EG24N9ES2K4/B10P4,5 combines both and works with up to 900 l/min at 280 bar.

Benefits

• Pilot oil taken internally, drained externally, one feed line less while the pilot return stays separate.
• 900 l/min flow in size 32 on the ISO 4401-10-09-0-05 pattern.
• 280 bar maximum operating pressure, spool symbol T with 3 switching positions.
• 36.75 kg weight, solenoid actuation at 24 VDC through a 3-pole (2 + PE) plug.
• NBR seals for HL hydraulic fluid, 4 ports and wiring to EN 175301-803.

Applications

The valve is meant for power units without a separate pilot pump, for example on presses, stretching lines and large hoists. The pilot return goes into a line of its own so that switching shocks in the main return do not reach the pilot stage. It requires sufficient pressure in the main channel to keep the pilot circuit supplied.
