It controls the start, stop and direction of flow and mainly consists of a housing (1), the solenoid (2), the valve seats (7) and (11) as well as of the closing element (4). The manual override (6) allows for the switching of the valve without solenoid energization. Basic principle (3/2 directional seat valve) The initial position of the valve (normally open "UK" or normally closed "CK") is determined by the arrangement of the spring (5). The chamber (3) behind the closing element (4) is connected to port P and sealed against port T. Thus, the valve is pressure-compensated in relation to the actuating forces (solenoid and spring). With the special closing element (4), ports P, A and T can be loaded with the maximum operating pressure (350 bar) and the flow can be directed into both directions (see symbols)! In the initial position, the closing element (4) is pressed onto the seat (11) by the spring (5), in spool position, it is pressed onto the seat (7) by the solenoid (2). The flow is blocked. With the 2/2 directional seat valve, the tank port is internally closed. 2/2 directional seat valve 3/3 directional seat valve „PK“ „UK“ „NK“ „CK“ Type M-3SED 6 UK1X/350CG24N9K4 (top) / type M-3SED 6 CK1X/350CG24N9K4 (bottom) 4/2 directional seat valve 2/2 and 3/2 directional seat valve With a sandwich plate, the Plus-1 plate , under the 3/2 directional seat valve, the function of a 4/2 directional seat valve is achieved. Function of the Plus-1 plate Initial position: The main valve is not operated. The spring (5) holds the closing element (4) on the seat (11). Port P is blocked and A is connected to T. A control line is connected from A to the large area of the control spool (8), which is thus unloaded to the tank. The pressure applied via P now pushes the ball (9) onto the seat (10). Thus, P is connected to B and A is connected to T. Transition position: Upon actuation of the main valve, the closing element (4) is shifted against the spring (5) and pressed onto the seat (7). During this, port T is blocked, while P, A, and B are briefly connected to each other. Switching p
