Directional Spool Valve 4WEH16J7X/6EG24N9EK4/10B08 - Bosch Rexroth R900924004

The 4WEH16J7X/6EG24N9EK4/10B08 combines internal pilot oil supply with external pilot oil return. Control pressure therefore comes from the main circuit while the control oil drains without back pressure into a separate line. Spool symbol J works in three switching positions, the valve carries 300 l/min at 280 bar and weighs 10.22 kg.

Benefits

• Internal pilot oil supply with external return, control oil stays clear of the tank line
• 300 l/min flow at 280 bar maximum operating pressure
• Spool symbol J over 3 switching positions and 4 ports
• ISO 4401-07-07-0-05 mounting pattern, 10.22 kg
• 24 VDC solenoid actuation, 3-pole connector (2 + PE) to EN 175301-803
• NBR seals for HL hydraulic fluid

Technical data

Application

This combination is chosen when back pressure builds up in the tank line and would upset the piloting. Control oil then runs straight to tank through a line of its own. Press controls and test rigs with long return paths are common places for it.

Manufacturer
