Directional Spool Valve 4WEH16J7X/6EG24N9ES2K4/B15 - Bosch Rexroth R901021647

The 4WEH16J7X/6EG24N9ES2K4/B15 takes its pilot oil internally from the main circuit, while the pilot oil return leaves the valve through a separate line. The pilot-operated main spool thus routes up to 300 l/min in size 16 according to spool symbol J.

Benefits

• Internal pilot oil supply, no separate pressure source is needed for the pilot stage.
• External pilot oil return for systems with a loaded return line.
• 300 l/min flow in size 16 to connection diagram ISO 4401-07-07-0-05.
• Spool symbol J with 3 switching positions on 4 ports.
• 280 bar maximum operating pressure at 10.84 kg.
• 24 VDC solenoid actuation through a 3-pole connector (2 + PE) according to EN 175301-803.

Technical data

Applications

This version fits axes whose pump keeps pressure up during operation, such as presses and feed drives on a constant pressure network. Pilot oil is then available without a dedicated pilot pump, while the return of the pilot valve is carried away separately. Mounting is on a subplate to ISO 4401-07-07-0-05.
