Directional Spool Valve H-4WEH25J6X/6EG24K4QM0G24/B10 - Bosch Rexroth R901030120

The centre position of a directional valve decides whether a load is held, released or circulated. The H-4WEH25J6X/6EG24K4QM0G24/B10 does this with spool symbol J at a flow of 700 l/min.

Benefits

• Spool symbol J with 3 switching positions and 4 ports
• 700 l/min at a maximum of 350 bar in the ISO 4401-08-08-0-05 interface
• External pilot oil supply and external return, independent of the state of the main circuit
• 24 VDC through a 3-pole (2 + PE) connector to EN 175301-803
• 18.6 kg in size 25, NBR seals, HL hydraulic fluid

Applications

The version is used in hoists and presses whose cylinders need a defined port arrangement in the centre position. A valve with a different symbol would change how the machine behaves with the solenoids off. Piloting works from a separate pilot circuit.

Manufacturer
