Directional Spool Valve H-4WEH25D6X/6EG24TSK4QMBG24 - Bosch Rexroth R901522464

Pilot oil from outside, drain to the inside: this combination fits manifolds with their own pilot pump but no separate drain. The H-4WEH25D6X/6EG24TSK4QMBG24 is built that way and carries up to 700 l/min at 350 bar.

Benefits

• External pilot supply, internal pilot drain, no separate drain line required.
• 700 l/min at 350 bar on the ISO 4401-08-08-0-05 pattern.
• Spool symbol D, 2 switching positions, subplate mounting in size 25.
• 17.8 kg, NBR seals for HL hydraulic fluid.
• 24 VDC solenoid actuation through a 3-pole (2 + PE) plug to EN 175301-803.

Applications

The valve is used on main axes of presses and drawing lines whose manifold provides only one pilot oil feed. Internal drain routing leads the pilot oil into the tank channel of the valve, so one fitting less is needed. It requires low back pressure in the return so that the pilot stage shifts cleanly.
