The 4WEH16G7X/6EG24N9S2DK25L directional spool valve belongs to the WEH Directional Spool Valves series manufactured by Bosch Rexroth. Intended for hydraulic automation, it is an electro-hydraulic 4-way unit in size NG16 that directs pressure and tank lines through a spool arranged in three positions with symbol G. Actuation is provided by a 24 V DC solenoid and can be performed locally with a concealed manual override. Pilot oil is fed externally via port X and returned through port Y, and spool movement is controlled by an integrated 4WE 6E pilot valve.
The valve supports a maximum flow of 300 l/min at 70 bar and withstands operating pressures up to 280 bar on ports P, A, and B. Its pilot circuit tolerates up to 250 bar and requires a minimum of 14 bar to move the spring-centered spool, while switching times can be tuned through discharge control. The unit mounts to manifolds that conform to ISO 4401-07-07-0-05, integrating quickly into NG16 subplate systems. These capabilities allow the 4WEH16G7X/6EG24N9S2DK25L to execute dependable directional changes in automated hydraulic machinery.
