Directional Spool Valve 4WEH16Y7X/6EG24N9ES2K4/B10 - Bosch Rexroth R901206465

The 4WEH16Y7X/6EG24N9ES2K4/B10 operates in two stages: the solenoid moves a small pilot stage, which then shifts the main spool hydraulically. That is how 300 l/min in size 16 stay controllable on 24 VDC. Pilot oil is taken internally and returned externally, spool symbol Y occupies two switching positions and the weight is 10.46 kg.

Benefits

• Pilot-operated, so 300 l/min flow remains controllable on 24 VDC solenoid actuation
• 280 bar maximum operating pressure in size 16
• Spool symbol Y, 2 switching positions, 4 ports
• Internal pilot oil supply with external return
• Subplate mounting ISO 4401-07-07-0-05, 10.46 kg
• 3-pole connector (2 + PE) to EN 175301-803, NBR seals

Application

The pilot stage needs a minimum pressure before the main spool reverses safely. If circuit pressure falls below that figure, the valve stays put even with voltage applied. In circuits with an unloading phase the control oil source therefore has to be picked with care.
