Directional Spool Valve H-4WEH25D6X/6EG24NTSK4 - Bosch Rexroth R900924520

The manifold supplies pilot oil, yet no extra line should be routed for the return. The H-4WEH25D6X combines external pilot oil supply with internal pilot oil return and switches 700 l/min.

Benefits

• External pilot oil supply with internal pilot oil return, which saves one line in the manifold.
• 700 l/min of flow in size 25 at a maximum of 350 bar.
• Spool symbol D with two switching positions across four ports.
• 18.58 kg, subplate mounting to ISO 4401-08-08-0-05.
• 24 V DC solenoid through a 3-pole connector (2 + PE) to EN 175301-803, NBR seals.

Applications

This combination is chosen in presses, steelworks equipment and large power units with shared pilot supply. The internal return saves a bore in the manifold and simplifies the assembly. At 700 l/min the valve stays within the rating of size 25.
