The 4WEH16G7X/6EW110N9SDA directional valve is built by Bosch Rexroth for the WEH Directional Spool Valves series. It regulates hydraulic flow and direction in automated circuits. The valve uses the ISO 4401-07-07-0-05 porting pattern, making it compatible with NG16 subplates. Its 4-way configuration and three spool positions allow forward, neutral, and reverse functions in closed-loop systems. A concealed manual override permits local actuation without exposing moving parts to contaminants. The DIN EN 175301-803 electrical connector offers standardized solenoid wiring for rapid replacement in the field. Fluid entering the unit must meet ISO 4406 class 20/18/15 cleanliness so that internal seals and lands remain wear-free.
The valve supports a maximum operating pressure of 280 bar and can pass 210 liters per minute at that pressure when the symbol G spool is installed, enabling high-flow servo tasks. The pilot stage works between 14 bar and 250 bar, while the internal X pilot line can initiate shifting at 4.5 bar; pilot return through port Y is rated up to 160 bar. Port T also tolerates up to 250 bar, allowing back-pressure in restricted return circuits. The pilot volume for the three-spool NG16 body is 5.72 cm³, providing fast response with limited oil demand. The mean time to dangerous failure is calculated at 100 years, supporting safety-related machinery categories.
