Directional Spool Valve H-4WEH25H6X/6EG12N9TDAL - Bosch Rexroth R901127459

Where a consumer needs more oil than a direct actuated valve can pass, this pilot-operated size 25 spool valve takes over the reversal. It carries up to 700 l/min, works in 3 switching positions to symbol H and withstands an operating pressure of 350 bar maximum.

Benefits

• Flow of up to 700 l/min in size 25, laid out for presses and power units moving a lot of oil
• Symbol H with 3 switching positions and 4 ports, all ports blocked in mid-position
• Pilot-operated design with external pilot oil supply and internal pilot oil return, so the pilot pressure can be provided independently of the working pressure
• Solenoid voltage 12 VDC, suited to the on-board supply of mobile power units
• Subplate mounting to ISO 4401-08-08-0-05 at a mass of 17.74 kg
• NBR seals for HL hydraulic fluid, electrical connection through a cable gland

Applications

The valve drives cylinders and hydraulic motors in presses, injection moulding machines and large power units. External pilot oil supply suits circuits whose working pressure drops below the required pilot pressure at times. Size 25 calls for a subplate dimensioned to match.
