Directional Spool Valve 4WEH16E7X/6EG48N9ETK4/B10 - Bosch Rexroth R901211766

Inside the 4WEH16 series each variant fixes three things: the connections given by the spool symbol, the voltage of the solenoid coil and the path taken by pilot oil. On the 4WEH16E7X/6EG48N9ETK4/B10 those are spool symbol E, 48 VDC, plus internal supply and internal return of control oil.

Benefits

• Spool symbol E in three switching positions across four ports.
• Coil voltage 48 VDC on a connector, 3-pole (2 + PE) according to EN 175301-803.
• Internal control oil routing on supply and return without ports X and Y.
• Flow of up to 300 l/min at a maximum operating pressure of 280 bar.
• Weight of 9.78 kg with NBR seals for HL hydraulic fluid.

Application

Because the variants look almost identical from outside, a replacement should be checked against the full type designation on the nameplate. If spool symbol or coil voltage differ, the machine behaves differently or the solenoid fails to pull in. This version suits circuits with permanent pressure at port P and a largely unloaded tank port.
