The 4WEH10G4X/6EW127N9DA SO43A-1058A spool valve is produced by Bosch Rexroth within the WEH Directional Spool Valves series. It is an electro-hydraulic unit intended to shift flow paths in automated hydraulic circuits. The valve is built in size NG10, allowing standard flow rates for medium frame manifolds. A subplate mounting interface with the ISO 4401-05-05-0-05 pattern aligns the pressure, tank, and work ports for quick replacement. The actuator section operates at up to 280 bar on ports P, A, and B so it fits high-pressure industrial systems, while port T can also handle 280 bar when Y is routed externally. A concealed N9 manual override lets maintenance staff shift the spool during commissioning or power loss without exposing moving parts.
Pilot operation is handled by a 4WE 6E control valve, which drives the main stage once an internal pilot line reaches at least 7.5 bar and stays below the 250 bar pilot limit. Hydraulic fluid must conform to DIN 51524, and system cleanliness must achieve ISO 4406 class 20/18/15 to protect the precision edges of the spool. A maximum surface coating thickness of 100 µm guards the housing against corrosion without interfering with mounting clearances. The valve’s mean time to dangerous failure is 100 years, supporting long service intervals in critical machines. These characteristics combine to deliver reliable directional control in electro-hydraulic power units.
