Directional Spool Valve H-4WEH25C6X/6EG24NK4/11 - Bosch Rexroth R900979182
Anyone reversing oil flows of up to 700 l/min in presses or large power units needs a pilot-operated directional valve in size 25. This version runs two switching positions with spool symbol C at an operating pressure of up to 350 bar. A 24 V DC solenoid does the switching.

Description
The task of this valve is to reverse large oil flows. Up to 700 l/min pass across the ISO 4401-08-08-0-05 mounting pattern at a maximum operating pressure of 350 bar. The two-position version with spool symbol C is pilot-operated, taking external pilot oil supply and external pilot oil return.
Benefits
- 700 l/min flow at up to 350 bar operating pressure in size 25
- Two switching positions with spool symbol C, so the end positions are clearly defined without an intermediate stage
- Subplate mounting to ISO 4401-08-08-0-05, fits the standard subplate of this size
- Solenoid actuation at 24 V DC, connector 3-pole (2 + PE) according to EN 175301-803
- NBR seals for HL hydraulic fluid, 18.31 kg weight
Application
Typical locations are presses, machine tools and power units where a cylinder or hydraulic motor is reversed at high flow. External pilot oil supply and return keep the pilot stage independent of the pressure in the main circuit. HL fluid and NBR seals suit standard industrial hydraulics.
Manufacturer
Bosch Rexroth lists the valve under material number R900979182. Characteristic curves, installation dimensions and the complete switching symbol are in the datasheet for this article.
