1)
Plug-in connectors must be ordered separately
(see page 3).
2)
For the connection to an AC supply a DC solenoid
must be used which is controlled via rectifi er (see
table on the left).
For individual connections a large plug-in connector
with integrated rectifi er can be used (separate order,
see page 3).

General:
The type M-.SEW directional valve is a solenoid operated
directional poppet valve. It controls the start, stop and direction
of a fl ow. It basically consists of a housing (1), the solenoid (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 is 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 630 bar.
Note:
• The 3/2-way poppet valves have a “negative switching
overlap”. Therefore port T must always be connected.
This means that during the switching process – 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, how-
ever 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 energising the solenoids.
• Care has to be taken to ensure that the stated maximum fl ows
are not exceeded! If necessary a cartridge throttle for fl ow
limitation has to be fi tted (see below).
