Directional Spool Valve 4WEH16D7X/6EG24N9EDL1/B10 - Bosch Rexroth R901062449

From size 16 upwards the force of a solenoid alone no longer moves the spool against the flow forces. The pilot-operated 4WEH16D7X/6EG24N9EDL1/B10 directional spool valve solves this with a hydraulic pilot stage and reverses up to 300 l/min at a maximum of 280 bar.

Benefits

• 300 l/min at a maximum of 280 bar operating pressure in size 16.
• Symbol D with two switching positions and four ports for reversing double-acting cylinders.
• Internal pilot oil supply with external pilot oil return, which keeps the return independent of the tank pressure in the main circuit.
• Subplate mounting to ISO 4401-07-07-0-05, so the hole pattern stays standard.
• Cable gland and 24 VDC, connection description to EN 175301-803.
• 12.58 kg, NBR seals, HL hydraulic fluid.

Applications

Typical locations are presses, injection moulding machines and lifting gear with large cylinder volumes. Because pilot oil is taken internally, no separate pilot pressure line is required. External pilot oil return pays off wherever back pressure builds up in the tank line of the main circuit.
