The 4WE6D73-6X/EW110RN9DAL/A12/62SO9 CSA directional valve is produced by Bosch Rexroth within the WE Directional Spool Valves series for controlling actuator flow in hydraulic automation. It fits nominal size 6 cavities that follow the ISO 4401-03-02-0-05 porting pattern. The solenoid operates from a 110 V AC supply at 50 or 60 Hz and draws a rated current of 0.34 A. During excitation the coil demands 220 VA switch-on power and then holds position with 50 VA. A 1/2-14 NPT cable gland forms the electrical entry, and the coil can remain energized continuously because the duty cycle is 100%. The housing carries an IP65 rating against dust and water jets. When required, a concealed manual override allows local spool actuation without electrical power.
In operation the valve handles flow rates up to 60 L/min while permitting 350 bar on ports P, A, and B. The tank port withstands back pressure to 160 bar. Spool shifts may occur at a maximum frequency of two cycles per second, supporting rapid machine sequences. Hydraulic fluid must meet cleanliness class ISO 4406 20/18/15 to protect internal surfaces. The assembly weighs 1.95 kg with two solenoids, aiding quick installation on a manifold. These capabilities combine to provide reliable directional control in automated hydraulic circuits.
