Directional Spool Valve H-4WEH25HD6X/OF6EG24N9TK4 - Bosch Rexroth R900755253

On the H-4WEH25HD6X/OF6EG24N9TK4 pilot oil arrives externally but returns internally. That simplifies piping without limiting the flow of up to 700 l/min or the 350 bar operating pressure.

Benefits

• External pilot oil supply, internal pilot oil return
• Flow up to 700 l/min at 350 bar operating pressure
• Two switching positions to spool symbol D, four ports
• Size 25 on the ISO 4401-08-08-0-05 pattern
• 17.5 kg weight, NBR seals and HL hydraulic fluid
• 24 VDC, connector 3-pole (2 + PE) to EN 175301-803

Application

Internal return pays off in compact control blocks where every extra bore costs space. Typical consumers are large differential cylinders in presses and forming lines. The tank passage must be able to take the pilot return without back pressure.

Manufacturer

The Bosch Rexroth material number is R900755253. Pilot oil demand, curves and permissible back pressures are documented in data sheet RE 24751, with RE 07600-B as supplement.
