DESCRIPTION APPLICATION
Direct operated solenoid spool valve with 4 connections in 5 cham- Spool valves are mainly used for controlling direction of movement
ber design. Spool detented or with spring reset. With the solenoids and stopping of hydraulic cylinders and motors. Switching perfor-
deenergised, the spool is held in the center position by the spring mance and leakage of the valves must be taken into account when
(4/3), or switched back to the offset position (4/2). With the impulse designing the system. Solenoid spool valves are suitable for machi-
