The 4WEH32G6X/6EG24N9SDA valve is manufactured by Bosch Rexroth for the WEH Directional Spool Valves series and serves to route pressurized fluid in automated hydraulic machinery. It operates with a 4-way configuration so four ports manage supply and return paths, and the internal flow pattern is defined by the G spool symbol. Connection to a subplate follows the ISO 4401-10-09-0-05 porting pattern, while a 4WE 6E pilot stage shifts the main spool. Actuation uses a 24 V DC solenoid, but a concealed manual override lets technicians move the spool without power. Switching time can be adjusted through a supply-control feature, allowing matched response to system dynamics. Spring-centered return demands at least 8.5 bar pilot pressure to hold an actuated position.
The nominal size NG32 supports flows up to 1100 l/min, making the valve suitable for high-capacity circuits. Maximum operating pressure at ports P, A, and B is 280 bar, and the pilot supply may reach 250 bar without overstressing control components. Port T accepts backpressure to 250 bar, while the external Y drain is limited to 210 bar in direct-current use. Hydraulic cleanliness must at minimum meet ISO 4406 class 20/18/15 to avoid abrasion within precision clearances. The unit weighs 41.0 kg, reflecting a robust housing that accommodates the stated pressures.
