DCV 05 directional control valves consist of: housing, control spool, centering springs, and operating solenoids. The three-position directional valves have two solenoids and two springs. The two position directional valves have one solenoid and one return spring. The operating solenoids are DC and are supplied through connectors A and B. For AC supply, the solenoids are provided with rectifiers integrated directly into the coil. The connectors must be ordered separately. By loosening nut, the solenoid can be rotated in four positions 90° apart. Provided that the pressure in T-port does not exceed 360 psi [25 bar], the valve can be actuated by manual override. The valve housing is phosphate coated. The operating solenoids are zinc coated.
