Directional Spool Valve H-4WEH25HL6X/6EG24N9SK4 - Bosch Rexroth R900941223

When large cylinders are brought down, the centre position decides how the load is held or released. The H-4WEH25HL6X/6EG24N9SK4 uses spool symbol L in size 25 for that and carries up to 700 l/min at a maximum of 350 bar.

Benefits

• Spool symbol L across three switching positions for a deliberately ported centre.
• 700 l/min flow through four ports on the ISO 4401-08-08-0-05 interface.
• 350 bar maximum operating pressure in the pilot operated design.
• 18.31 kg weight, a figure that affects assembly and carrier design.
• 24 V DC with a 3-pole connector (2 + PE) to EN 175301-803.

Application

The valve goes into power units for presses, lifting gear and large clamping systems. External pilot oil supply with external return allows a separate control oil feed, for example from an auxiliary circuit.
