Directional Spool Valve H-4WEH25HD6X/OF6EG24N9TS2K4/B08 - Bosch Rexroth R901111606

An existing subplate can rarely be drilled for an extra pilot line after the fact. The H-4WEH25HD6X/OF6EG24N9TS2K4/B08 therefore passes its pilot oil internally into the tank line while taking it from outside, and switches up to 700 l/min at a maximum of 350 bar.

Benefits

• Internal pilot oil return with external pilot oil supply, no extra bore in the block.
• Spool symbol D in two switching positions across four ports.
• 700 l/min in size 25 at a maximum operating pressure of 350 bar.
• 3-pole connector (2 + PE) to EN 175301-803, 24 V DC solenoid actuation.
• 18.8 kg weight, NBR seals, connection diagram ISO 4401-08-08-0-05.

Application

The combination suits retrofits where a new valve goes onto an older subplate. The condition is a tank line that builds up little counter pressure in service.
