Directional Spool Valve 4WEH16E7X/6EG24N9EK4/B10SO8 - Bosch Rexroth R901116627

Internal pilot oil supply with external pilot oil return keeps the pilot drain clear of the pressure in the return line. The size 16 main spool releases up to 300 l/min and works in three switching positions to symbol E.

Benefits

• External pilot oil return keeps the switching action independent of back pressure in the tank line
• Internal pilot oil supply removes the need for a separate pressure line for pilot oil
• Flow of up to 300 l/min at an operating pressure of up to 280 bar
• Three switching positions to symbol E across four ports on the ISO 4401-07-07-0-05 interface
• Solenoid actuation at 24 VDC with a 3-pole connector (2 + PE) according to EN 175301-803
• Subplate mounting in size 16, NBR seals, valve weight of 9.32 kg

Applications

This pilot arrangement is chosen where filters, coolers or long lines build up back pressure in the return. Power units of presses, test rigs and steel plant are typical. Size 16 with 300 l/min serves cylinders of large bore there.
