Directional Spool Valve 4WEH16D7X/6EG24N9ETS2K4/B10P4,5 - Bosch Rexroth R900741664

Handling 280 bar and 300 l/min at the same time calls for hydraulically amplified actuation. That is exactly what the pilot-operated directional spool valve 4WEH16D7X/6EG24N9ETS2K4/B10P4,5 provides, its 24 VDC pilot valve shifting the large main spool of size 16.

Benefits

• Maximum operating pressure 280 bar at a rated flow of 300 l/min.
• Hydraulically amplified actuation, the 24 VDC solenoid drives only the pilot valve.
• Four ports in two switching positions to symbol D, mounting pattern ISO 4401-07-07-0-05.
• Internal pilot oil supply and internal pilot oil return without extra lines on the manifold.
• 3-pole connector (2 + PE) according to EN 175301-803, NBR seals for HL hydraulic fluid.
• 10.58 kg for the assembled pilot and main stage.

Applications

Valves of this kind sit in presses, lifting gear and test rigs whose cylinders move large volumes of oil at high pressure. Two-stage actuation keeps the electrical power small even though the main spool works against 280 bar. Subplate mounting allows an exchange against other size 16 versions without altering the piping.
