Industrial hydraulic valve in a high performance range, reliable switch of oil flow direction according to hydraulic symbol

Unpacked Weight: 2.423 kg

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).

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.

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.

Seat valves can be used according to the spool symbols as well as the assigned operating pressures and flows (see performance limits).

In order to ensure a safe functioning, it is absolutely necessary to observe the following:

In order to switch the valve safely and/or maintain it in its spool position, the pressure must be pP ≥ pA ≥ pT (for design reasons). Seat valves have a negative spool overlap, i.e. leakage oil occurs during the switching process. However, this process takes place within such a short time that it is irrelevant in nearly all cases of use. The specified maximum flow must not be exceeded (use a throttle insert for flow limitation, if necessary)!

Plus-1 plate:

When using the Plus-1 plate (4/2 directional function), the following lower operating values are to be observed: pmin = 8 bar; qV > 3 l/min. The ports P, A, B and T are clearly specified according to their tasks. They must not be arbitrarily exchanged or closed! With 3- and 4-way spool position, port T must always be connected. Observe the pressure level and pressure distribution! The flow is only admissible in the direction of arrow!
