Directional Spool Valve H-4WH25E6X/QM0G24SO746 - Bosch Rexroth R900930871

Some control systems give their signal hydraulically rather than electrically. The H-4WH25E6X/QM0G24SO746 is therefore hydraulically actuated and controls up to 700 l/min in size 25.

Benefits

• Hydraulic actuation, driven through the pilot oil circuit instead of a solenoid.
• 700 l/min maximum flow at 350 bar maximum operating pressure.
• External pilot oil supply and external pilot oil return through X and Y.
• Spool symbol E in three switching positions with four ports.
• 16.62 kg mass, connection diagram ISO 4401-08-08-0-05, NBR seals.

Applications

It is used in manifolds where an upstream valve applies the pilot pressure, for example in presses and steel plants. Doing without a solenoid saves an electrical interface inside the manifold. The released hydraulic fluid is HL.
