Function and configuration

·Type M-SED10 3/2 directional poppet valve

Directional valves of the type SED are direct operated directional poppet valves with solenoid actuation.

They control the start, stop and direction of flow.

The directional poppet valves consist of housing (1), the solenoid (2), the valve seat (7) and (11) and the control spool (4).

The manual override (6) allows for the switching of the valve without solenoid energization.

General principle (3/2 directional poppet 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 control spool(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).

By means of the control spool (4),the port P,A and T can be loaded with maximum operating pressure (350bar) and the flow can be directed in both directions (see symbols).

In the initial position, the control spool (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.

·Type M-4SED10 4/2 directional poppet valve

With a sand with plate, the Plus-1plate, under the 3/2 directional poppet valves, the function of a 4/2 directional poppet valve is achieved.

1). Initial position:

the main valve is not actuated. The spring(5)holds the control spool(4)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(8), which is thus unloaded to the tank. The pressure applied via P now pushes the ball(9) onto the seat(10). Now, P is connected to B, and A to T.

2). Transition position:

When the main valve is actuated, the control spool(4) is shifted against the spring(5) and pressed onto the seat(7). During this, port T is blocked, P, A, and B are briefly connected to each other.

3). Spool position:

P is connected to A.As the pump pressure acts via A on the large area of the control spool (8), the ball (9) is pressed onto the seat (12). Thus, B is connected to T, and P to A. The ball (9) in the Plus-1 plate has a "positive spool overlap".

·Throttle insert:

The use of a throttle insert is required, if, due to the operating conditions, flows are to be expected during the switching procedure, which are higher than the started maximum performance limits of the valve.

The throttle is inserted into port P of the valve.

·Cartridge check valve:

The cartridge check valve allows free flow from P to A and provides leak-free closed from A to P.

The cartridge check valve is inserted into port P of the valve.
