Directional Spool Valve 4WEH16D7X/6EG24N9EK4K/B10P4,5 - Bosch Rexroth R900707447

The spool of this valve is not moved by the solenoid itself but through a pilot stage. That allows up to 300 l/min to be switched in size 16, at a maximum operating pressure of 280 bar.

Benefits

• Two switching positions to symbol D at a rated flow of 300 l/min.
• Internal pilot oil supply, so no separate feed line for the pilot stage is needed.
• External pilot oil return, keeping the pilot return clear of the tank pressure in the working circuit.
• Subplate mounting to ISO 4401-07-07-0-05, the valve sits on the subplate without an adapter.
• Solenoid for 24 VDC with a 3-pole connector (2 + PE) to EN 175301-803, NBR seals for HL hydraulic fluid, 9.46 kg in weight.

Applications

Size 16 covers cylinders and hydraulic motors that take large oil volumes in rapid traverse, for example on presses, forging equipment and lifting gear. A two-position version belongs where an axis shuttles between two end positions and needs no bypass centre. The internal supply saves one pilot line in the manifold, while the separate return keeps the pilot pressure steady.
