Directional Spool Valve H-4WEH25C6X/6EG24NK4/11 - Bosch Rexroth R900979182

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

Technical data

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.
