Product Overview
The Rexroth 4WE 6 HB62/EG24N9K4=00 (Material Number: R900951971) is a high-performance direct-operated solenoid directional spool valve from the proven Rexroth 4WE 6 series. Designed according to ISO 4401 / DIN 24340 size 6 (NG6 / CETOP 3) interface standards, this valve controls the start, stop, and direction of hydraulic fluid flow in industrial power circuits. The “HB” spool designation provides a specific mid-position configuration (closed center with restricted flow characteristics), while the EG24N9K4 solenoid configuration denotes a 24 V DC high-power wet-pin solenoid with a concealed manual override and a standard DIN EN 175301-803 (ISO 4400) connector. This valve is engineered for precise, repeatable switching in demanding hydraulic systems requiring reliable directional control.
