It controls the start, stop and direction of flow. It mainly comprises a housing (1), the solenoid (2), the hardened valve system (3) as well as the ball (4) as closing element. Basic principle In the initial position, the ball (4) is pressed onto the seat by the spring (8) and by the solenoid (2) in switching position. The force of the solenoid (2) acts via the angled lever (5) and the ball (6) on the actuating plunger (7), which is sealed. The chamber between the two sealing elements is connected to port P. Therefore, the valve system (3) is pressure-compensated in relation to the actuating forces (solenoid or return spring). Therefore, the valves can be used up to 630 bar. Notice! 3/2-directional seat valves feature "negative spool overlap". Therefore, port T must always be connected. That means that during the switching process – from the starting of the opening of one valve seat to the closing of the other valve seat – ports P–A–T are connected with each other. However, this process takes place within such a short time that it is irrelevant in nearly all cases of use. The manual override allows for the switching of the valve without solenoid energization. Attention! It is to be ensured that the maximum flow indicated is not exceeded! If applicable, a throttle insert for flow limitation is to be inserted (see functional description). The seat arrangement offers the following options: Symbol „U“ Initial position P and A connected, T blocked Switching positions P blocked, A and T connected Symbol „C“ Initial position P blocked, A and T connected Switching positions P and A connected, T blocked Type .-3SE 6 U … 3/2 directional seat valve – with detent In principle, the function of this valve corresponds to the version without detent. The detent enables the valve to stay in the switched position even if no solenoid is energized. This allows the valve to independently stay in both switching positions. Detent function: The solenoid (2) switches the valve into the switching position, which is latched automatically. The switching solenoid can be switched off once the switching process has been completed. In order to leave the latched position, the solenoid (9) must be switched for a minimum of 100 ms. With the installed spring (16), the valve is returned to its basic position. The seat arrangement offers the following options:
