Directional Spool Valve 4WEH16G7X/6EG24NETK4/B10P4,5 - Bosch Rexroth R900968510

Where the manifold has no dedicated pilot circuit, this version of the 4WEH16 handles pilot oil supply and return internally while switching up to 300 l/min. Three positions to spool symbol G, a maximum operating pressure of 280 bar and a 24 VDC solenoid define its working range.

Key benefits

• Internal pilot oil supply and internal return save two lines in the manifold, the valve works with the four ports of the subplate alone.
• 300 l/min maximum flow in size 16 to connection diagram ISO 4401-07-07-0-05.
• 280 bar maximum operating pressure for axes reversed under load in continuous duty.
• Spool symbol G across three switching positions, shifted by solenoid actuation at 24 VDC.
• Connector, 3-pole (2 + PE) according to EN 175301-803 for direct control from the machine controller.
• 9.92 kg weight with NBR seals for hydraulic fluid HL.

Technical data

Applications

The valve sits in control manifolds of presses, hoists and power units where pilot pressure is taken from the main circuit. Because supply and return are internal, the four ports of the ISO 4401-07-07-0-05 subplate are sufficient. For retrofits the valve can be exchanged for another unit of the same size on the same subplate. NBR seals and hydraulic fluid HL match standard mineral oil hydraulics.

Manufacturer
