Quick Reference Cartridge Valves Technical Information Directional Valves DCV 03 Directional control valves DCV03 DCV 03 directional control valves consist of: housing (1), control spool (5), with two centering springs (4), and cylindrical operating solenoids (2, 3). The three-position directional valves have two solenoids and two springs. Two-position directional valves have either one solenoid and one return spring or two solenoids and a detent assembly. The operating solenoids are DC. For AC supply the solenoids are provided with a rectifier, which is integrated directly into the coil. The plug connectors (6, 7) can be rotated 90°. By loosening the nut (8), the solenoids can be rotated 360°. This enables the solenoids to be replaced without opening the valves. In the case of solenoid malfunction or power failure, the spool can be actuated by manual override (9), provided the pressure in T-port does not exceed 25 bar [360 psi]. The valve housing (1) is phosphate coated. The operating solenoids (2, 3) are zinc coated. FEATURES 3 position, 4-way, and 2 position, 4way directional valves Cylindrical operating solenoids with separate operating coils – connector can be rotated 90° 4-land spool – reduced functional dependence on fluid viscosity Push button manual override

Quick Reference Cartridge Valves Technical Information Directional Valves DCV 03 Directional control valves DCV03 SPOOL SPEED CONTROL ORIFICE This directional valve provides cushioned control spool shifting by means of orifice situated in the solenoid armature. To ensure proper function, air bleeding required. To bleed : 1. Remove Boot (2) 2. Open Plug (1) 3. Tighten plug after air is removed 4. Replace boot P-PORT ORIFICE OPTIONS Description The orifice installed in the P port restricts the input flow.. P Orifices can also be used in all ports. Flow can be bidirectional. D
