General information
The 5/3 directional spool valves are direct operated, pressure-compensated screw-in cartridge valves. They control the start, stop and direction of flow and basically consist of pole tube (1), socket (2), a control spool (5) and a return spring (4).
Function
In the de-energized condition, the control spool (5) is held in the initial position by the return spring (4). The control spool (5) is actuated by wet-pin DC solenoids (3.1; 3.2). The symbols are realized by different spools ("10”; “20”). The main ports ➀, ➁, ➂, ➃ and ➄ can be pressurized continuously with an operating pressure of 250 bar. The ports have a fixed pin assignment (see Symbols).
The manual override (6) allows for the switching of the valve without solenoid energization.
