Directional Spool Valve 4WEH16HD7X/6EG24N9EK4/10B10 - Bosch Rexroth R900929581

Large spool cross sections can no longer be moved by a solenoid directly, which is what the pilot-operated design is for. The directional spool valve 4WEH16HD7X/6EG24N9EK4/10B10 in size 16 switches up to 300 l/min to symbol D.

Benefits

• Up to 300 l/min in size 16 to port pattern ISO 4401-07-07-0-05.
• Pilot-operated, the main stage is moved by a small pilot valve.
• Internal pilot oil supply, external pilot oil return, the return line stays decoupled.
• Symbol D in two switching positions across four ports, 24 VDC.
• Maximum operating pressure 280 bar, NBR seals, 9.68 kg, HL hydraulic fluid.

Technical data

Application

Hydraulic presses, injection moulding machines and large feed axes move oil quantities that call for size 16. The external pilot oil return keeps the pilot stage clear of surges in the return line, which keeps switching behaviour even. Subplate mounting puts all channels into the manifold.
