The 4WEH22E7X/6EW110N9DA directional spool valve belongs to the WEH Directional Spool Valves series and is manufactured by Bosch Rexroth. Intended for hydraulic automation, it directs flow between service ports under electrical pilot control. The valve is built in a 4/3 configuration, giving four ports and three spool positions for versatile circuit logic. It is assigned nominal size 25 (NG25), so it mounts in systems designed for that flow capacity. Electro-hydraulic actuation allows the main spool to shift through pilot pressure generated by a 6E pilot valve. The spool is cut to symbol E, permitting a rated flow of up to 450 l/min without excessive pressure drop. The housing follows porting pattern ISO 4401-08-08-0-05, and placement within the 7X component series keeps dimensions consistent for interchangeability.
System limits are defined by a maximum operating pressure of 280 bar on ports P, A, and B, while port T withstands up to 250 bar during return flow. The external pilot supply can be pressurized to 210 bar, and the spool centers once pilot pressure falls below the 10.5 bar minimum required for the spring-centered design. External pilot oil return prevents back-pressure from influencing spool response. A concealed manual override coded N9 allows local actuation during commissioning without increasing envelope size. Fluid entering the unit must meet ISO 4406 cleanliness class 20/18/15 to protect precision clearances and prolong service life. These limits and interface features support stable control of high-flow circuits in mobile or industrial hydraulic machinery.
