Directional Spool Valve H-4WEH25E6X/6EG24N9K4 - Bosch Rexroth R900932453

A return line carrying back pressure can disturb the pilot stage of a directional valve. This size 25 variant avoids that by routing both pilot oil supply and pilot oil return externally. It switches 700 l/min at a maximum of 350 bar using spool symbol E.

Benefits

• Pilot oil supplied and returned externally, independent of return line back pressure
• Spool symbol E with three switching positions and four ports
• 700 l/min rated flow at 350 bar maximum operating pressure
• 17.84 kg weight, interface ISO 4401-08-08-0-05
• 24 V DC through connector, 3-pole (2 + PE) according to EN 175301-803

Applications

The version suits circuits with a return filter or cooler where residual pressure builds up in the tank channel. In presses and forming lines the separated pilot routing keeps switching times consistent. An external pilot pressure supply must be available.
