Directional Spool Valve H-4WEH25HG6X/6EG24N9K4/B10 - Bosch Rexroth R901282137

A control block with high return back pressure disturbs the pilot stage whenever pilot oil drains internally. The H-4WEH25HG6X/6EG24N9K4/B10 routes both pilot oil supply and pilot oil return externally, works with spool symbol G and passes up to 700 l/min.

Benefits

• External pilot oil return keeps the pilot circuit clear of back pressure in the tank line.
• 700 l/min in size 25 at a maximum operating pressure of 350 bar.
• Spool symbol G with three switching positions across four ports.
• 3-pole connector (2 + PE) to EN 175301-803 for the 24 V DC solenoid actuation.
• 19.3 kg weight, NBR seals, connection diagram ISO 4401-08-08-0-05.

Application

The valve belongs in systems whose return line runs through filters or coolers and therefore builds up counter pressure. Shifting time stays predictable even when several valves work in parallel.

Manufacturer
