Directional Spool Valve 4WEH16J7X/6EG24N9ES2K4QM0G24/B10 - Bosch Rexroth R901249676

This size 16 valve is built for circuits whose tank line carries back pressure. Pilot oil is taken internally, while the return runs externally and stays independent of the return pressure in the main stage. Switching covers three positions with spool symbol J at up to 300 l/min and 280 bar.

Benefits

• Internal pilot oil supply with external pilot oil return, independent of back pressure in the tank line
• Spool symbol J with three switching positions and four ports
• 300 l/min across the subplate interface to ISO 4401-07-07-0-05
• 280 bar permissible operating pressure in size 16
• Solenoid actuation at 24 VDC, 3-pole connector (2 + PE) according to EN 175301-803
• 11.52 kg mass, NBR seals for HL hydraulic fluid

Application

The usual place for this valve is a power unit with a long return line or a return filter, where pressure builds up in the tank channel. The external pilot oil return is then routed on its own line and keeps switching times stable. A flow of 300 l/min covers long stroke cylinders in presses and test rigs.
