Directional Spool Valve 4WEH16E7X/6EG24N9ES2K4QMABG24/B10 - Bosch Rexroth R901109409

Spool symbol E, internal pilot oil supply and external return set the working range of this size 16 valve. Pilot oil comes from the pressure line of the main stage but leaves the pilot circuit through a line of its own. Control pressure therefore stays decoupled from the return of the main stage, even at 300 l/min and 280 bar.

Benefits

• Internal pilot oil supply with external return through a dedicated control line
• Spool symbol E with three switching positions across four ports
• 300 l/min on a connection diagram to ISO 4401-07-07-0-05
• 280 bar permissible operating pressure in size 16
• Solenoid actuation at 24 VDC with a 3-pole connector (2 + PE) according to EN 175301-803
• 11.56 kg mass, NBR seals for HL hydraulic fluid

Technical data

Application

Installation pays off where several valves work into a shared return line whose pressure fluctuates. The external return takes the pilot circuit out of that fluctuation. Fields of use are press hydraulics, rolling mill equipment and large cylinder drives up to 300 l/min.

Manufacturer

Bosch Rexroth lists this directional valve 4WEH16E7X/6EG24N9ES2K4QMABG24/B10 under material number R901109409. The data sheets Directional spool valves, pilot-operated (RE 24751) and Hydraulic valves and hydro- (RE 07600-B) carry the characteristic curves and installation dimensions. The Y port of the subplate has to be routed free for operation.
