Product description
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.

Attention!
The specified performance limits are valid for use with two directions of flow (e. g. from ➄ to ➁ and simultaneous return flow from ➃ to ➂). Due to the flow forces acting within the valves, the admissible performance limit may be considerably lower with only one direction of flow (e. g. from ➄ to ➁ while port ➃ is blocked)!
In such use cases, please consult us!
The performance limit was determined when the solenoids were at operating temperature, at 10 % undervoltage and without tank preloading.
