Directional Spool Valve H-4WEH25HD6X/6EG24NTK4 - Bosch Rexroth R900929468

The pilot circuit can be supplied separately and still be relieved internally. That is what this version delivers with external pilot oil supply and internal pilot oil return, at 700 l/min of flow and spool symbol D.

Benefits

• External pilot oil supply, internal pilot oil return, separate feed without a second return line.
• Flow up to 700 l/min in size 25, maximum operating pressure 350 bar.
• Spool symbol D with 4 ports and 2 switching positions.
• 17.51 kg weight, subplate mounting to ISO 4401-08-08-0-05.
• Solenoid actuation at 24 VDC, NBR seals, HL hydraulic fluid.

Application

The layout suits machinery with its own pilot pump or accumulator supply. Because the return stays inside the valve, the number of fittings on the manifold drops. The electrical connection is a 3-pole connector (2 + PE) to EN 175301-803.
