The Bosch Rexroth M-4SEW6D3X/420MG24N9K4/B18 (R900215870) is a high-performance directional seat valve with solenoid actuation designed to manage the start, stop, and direction of fluid flow in hydraulic systems. This valve is characterized by its robust housing, solenoid, hardened valve system, and spool that functions as the closing element. The unique construction allows for pressure compensation between the actuating forces of the solenoid or return spring, enabling it to function up to a maximum operating pressure of 315 bar.
The M-4SEW6D3X/420MG24N9K4/B18 valve features a manual override for non-electrical actuation and requires that port T always be connected due to its negative spool overlap design. This ensures a brief interconnection between ports P, A, and T during switching transitions which typically has negligible impact on performance. Furthermore, it can be configured with a throttle insert for flow limitation or a check valve insert for free flow in one direction and leak-free closure in the opposite direction.
This Bosch Rexroth directional seat valve comes in various versions including 2-way or 3-way configurations and adheres to porting patterns according to DIN form A and ISO standards. The airgap DC solenoids are equipped with detachable coils which are rotatable by 90 degrees and can be replaced without opening the pressure-tight chamber. For ease of electrical connection, it features individual connections with optional auxiliary operating devices such as inductive position switches and proximity sensors for contactless detection.
Designed for seamless integration into hydraulic systems, this model boasts a size X component series with a maximum flow rate of up to 60 liters per minute. Its versatility makes it suitable for various applications requiring precise control over fluid dynamics within hydraulic circuits.

2/2 and 3/2 directional seat valve
General
The SEW type directional valve is a directional seat valve with solenoid actuation. It controls the start, stop and direction of flow.
The valve basically consists of the housing (1), the solenoid (2), the hardened valve system (3) as well as the ball/the spool (4) as closing element.
Basic principle
In the initial position, the ball/the spool (4) is pressed onto the seat by the spring (9) and by the solenoid (2) in the switching position. The force of the solenoid (2) acts via the angled lever (6) and the ball (7) on the actuating plunger (8) that is sealed on two sides. 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.
Notices!
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 (10) allows for the switching of the valve without solenoid energization. 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).Type M-3SEW 6 U …
Type M-2SEW 6 N …
4/2 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 (9) holds the ball (4.1) on the seat (11). Port P is blocked and A is connected to T. Apart from that, one control line is connected from A to the large area of the control spool (12), which is thus unloaded to the tank. The pressure applied via P now pushes the ball (13) onto the seat (14). Now, P is connected to B, and A to T.
Transition position:When the main valve is actuated, the spool (4.2) is shifted against the spring (9) and pressed onto the seat (15). During this, port T is blocked, while P, A, and B are briefly connected to each other.
Switching position:P is connected to A. As the pump pressure acts via A on the large area of the control spool (12), the ball (13) is pressed onto the seat (16). Thus, B is connected to T, and P to A. The ball (13) in the Plus-1 plate has a "positive spool overlap".
Notices!
If the annulus area of differential cylinders is not connected to port A, a pressure peak is created in port B during the switching process due to the pressure intensification. This pressure peak may exceed the maximum operating pressure over the permissible limit.
Type M-4SEW 6 Y …
Throttle insert
The use of a throttle insert is required when due to prevailing operating conditions, flows can occur during the switching processes, which exceed the performance limit of the valve.
Examples:
Accumulator operation, use as pilot control valve with internal pilot fluid tapping.2/2- and 3/2 directional seat valve
The throttle insert is inserted into port P of the seat valve
.
4/2 directional seat valve (see functional description)
The throttle insert is inserted into port P of the Plus-1 plate.
Check valve insert
The check valve insert allows a free flow from P to A and closes A to P in a leak-free form.
2/2- and 3/2 directional seat valve (see functional description)
The check valve insert is inserted into port P of the seat valve.
4/2 directional seat valve (see functional description)
The check valve insert is inserted into port P of the Plus-1 plate.
