The 4WEH16D7X/6EW110N9DAL directional spool valve belongs to the WEH Directional Spool Valves series from Bosch Rexroth. It directs hydraulic flow to actuators in automated machinery where precise switching is required. Electro-hydraulic actuation converts an electrical pilot signal into spool movement so the control system can shift flow without large mechanical forces. A 4-way configuration establishes two discrete flow paths for extending and retracting cylinders. The NG16 size defines a 16 mm port envelope that balances compact dimensions with the ability to pass significant media. Maximum flow of 300 l/min lets the valve support high-capacity circuits, while a maximum operating pressure of 280 bar withstands common industrial supply levels. A 6E pilot control valve manages the pilot oil, and the ISO 4401-07-07-0-05 porting pattern matches standard subplates for quick installation.
Subplate mounting allows the body to sit on a manifold so maintenance crews can exchange the unit without disturbing hard plumbing. Four M10 × 60 screws according to ISO 4762 secure the housing, and each fastener must be tightened to 58 Nm to prevent external leakage. A concealed manual override lets technicians shift the spool manually during commissioning or power loss without exposing moving parts. The pilot stage tolerates up to 250 bar yet needs at least 14 bar in a two-spool arrangement to achieve reliable actuation. The valve’s mean time to dangerous failure is 100 years, supporting long service intervals in production equipment.
