Directional Spool Valve H-4WEH25E6X/6EG24N9TK4/12B10 - Bosch Rexroth R901326561
A manifold block with an unpressurised tank gallery can route the pilot return internally and save a line. This version of the H-4WEH25 does exactly that while drawing pilot oil externally. It switches 700 l/min following spool symbol E at 350 bar and weighs 18.34 kg.

Description
The H-4WEH25E6X/6EG24N9TK4/12B10 directional spool valve combines external pilot oil supply with internal pilot oil return. In size 25 it carries up to 700 l/min at a maximum operating pressure of 350 bar following spool symbol E.
Benefits
- External pilot oil supply, internal pilot oil return, one line fewer
- Flow up to 700 l/min at operating pressure up to 350 bar
- Spool symbol E, three switching positions, four ports
- Solenoid actuation at 24 VDC, 3-pole connector (2 + PE) to EN 175301-803
- ISO 4401-08-08-0-05 subplate mounting, NBR seals, weight 18.34 kg
Application
The combination suits plants that have a separate pilot pressure source while the tank gallery stays close to zero pressure. Presses and large test rigs are typical. Mounting is on a subplate to ISO 4401-08-08-0-05.
Manufacturer
Bosch Rexroth lists this valve under material number R901326561. The required pilot pressure is given in the manufacturer datasheet.
