Directional Spool Valve 4WEH16HD7X/OF6EG24N9ESK4/B10 - Bosch Rexroth R900971881

Connection diagram and pilot oil routing decide whether a valve fits an existing control block. The 4WEH16HD7X/OF6EG24N9ESK4/B10 sits on the ISO 4401-07-07-0-05 interface, draws its pilot oil internally from port P, drains the pilot oil return externally and directs up to 300 l/min while doing so.

Benefits

• ISO 4401-07-07-0-05 interface with four ports and subplate mounting.
• Internal pilot oil supply, external pilot oil return, the pilot drain runs its own path to tank.
• 300 l/min at a maximum of 280 bar operating pressure.
• 10.77 kg valve weight, size 16, spool symbol D.
• 24 VDC solenoid actuation with a connector, 3-pole (2 + PE) to EN 175301-803.

Technical data

Applications

The valve controls feed and lifting movements on cylinders drawing 300 l/min, for example on presses, shears and hoists. Since the pilot stage feeds off system pressure, no separate pilot source is required, although the pilot drain does need a line back to tank. NBR seals make it suitable for HL hydraulic fluid.
