Directional Spool Valve H-4WEH25HJ6X/6EG48NSK4 - Bosch Rexroth R901211941

A cylinder drive taking 700 l/min can no longer be switched by a solenoid alone. The pilot-operated directional spool valve H-4WEH25HJ6X/6EG48NSK4 carries that flow in size 25, holds 350 bar operating pressure and works with spool symbol J in three switching positions.

Benefits

• Flow up to 700 l/min in size 25, connection diagram ISO 4401-08-08-0-05.
• Operating pressure to 350 bar with NBR seals and HL hydraulic fluid.
• Spool symbol J with three switching positions and four ports.
• Solenoid voltage 48 V DC, 3-pole connector (2 + PE) to EN 175301-803.
• External pilot oil supply and external pilot oil return, weight 20.22 kg.

Applications

The valve controls large cylinders in presses, forging plants and lifting gear, where the main flow lies far above the range of directly operated valves. The external pilot supply keeps it working even when pressure in the main circuit drops for a moment.
