Functional description of solenoid actuated poppet directional valves
General:

The 2 type M-.SEW directional valve is a solenoid actuated directional poppet valve. They control the start, stop and direction of a flow. They basically consist of a housing (1),the solenoids (2),the hardened valve. system (3) and the ball(s) (4) as the closing element.

Basic principle:

In the initial position the ball (4) is pressed onto the seat by the spring (9), and in the switched position by the solenoid (2).

The solenoid (2) force acts via the lever (6) and the ball (7) on the actuator pin (8), which sealed on two sides.

The chamber between the two sealing elements is connected with port P. The valve system (3) is thereby pressure balanced with regard to the actuating forces (solenoid or return spring). The valves can, therefore, be used up to a pressure of 63MPa.

Note:

The 3/2-way poppet valves have a "negative switching overlap".

Therefore, port T must always be connected. This means that during the witching procedure from the start of opening one valve seat to the closing of the other seat - all of the ports P-A-T are connected with each other. This, however, takes place in such a short space of time that in most applications it is irrelevant. The hand override (10) makes it possible to switch the valve without energizing the solenoids. Care has to be taken to ensure that the stated maximum flows are not exceeded! If necessary a cartridge throttle for flow limitation has to be fitted (see below).

In conjunction with a sandwich plate, a plus-1 plate, under the 3/2-way poppet valve this valve can be used as 4/2-way poppet valve.

Function of the plus-1 plate:

Initial position:

The main valve is not actuated. The spring (9) holds the ball (4.1) on the seat (1i). Port F is closed and A is connected to T. In addition, a control line runs from A to the large area of the control spool (12), which is thus unloaded to tank. The pressure plied via P now moves the ball (13) onto seat (14).Thus, P is connected to B and A to T.

Translation position:

When the main valve is operated, the ball (4.2) is pushed against the spring (9) and then pressed onto the seat (15).Port T is then blocked, P,A and B are connected to each other for a short time.

Switched position:

P is connected to A. As the pump pressure acts via A on the large area of the control spool (12), ball (13) is pushed onto seat (16).Thus, B is connected to T and P to A. Ball (13) in the plus-l plate has a "positive switching overlap". In order to avoid pressure intensification when single rod cylinders are used, the annulus area of the cylinder must be connected to A.

Due to the use of the plus-1 plate and the arrangement of the seats, the following combinations are possible:
