Rexroth Original M-3SED Directional Seat Valve With Solenoid
Actuation
Size 6
Component series 1X
Maximum operating pressure 350 bar [5100 psi]
Maximum flow 25 l/min [6.6 gpm]
General
The directional valve type M-.SED is a direct operated directional
seat valve with solenoid actuation. It controls start, stop and
direction of the flow and basically comprises a housing
(1),solenoid (2), valve seats (7) and (11) and closing element (4).
The manual override (6) allows for the operation of the valve
without solenoid energization.
Basic principle (3/2 directional seat 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 closing element (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).
Due to the special closing element (4), ports P, A, and T can be
loaded with the maximum operating pressure (350 bar) and the flow
can be directed into both directions (see symbols). In the initial
position, the closing element (4) is pressed onto the seat (11) by
the spring (5), in operated position onto the
seat (7) by the solenoid (2). The flow is blocked.With the 2/2
directional seat valve, the tank port is blocked internally.
