A seat valve for controlling pneumatic or hydraulic pressure between at least two pressure fluid channels (8, 8') includes a valve closure member (5) connected to a magnetic armature (4), a spring for the basic positioning of the valve closure member (5) in relation to a valve seat (7) in the valve housing (6), a magnetic core and a valve coil for the translatory movement of the magnetic armature (4). A control channel (1), a tappet (2), a sleeve (2'), a rotating field winding (3), and an opening 3') are provided to produce a rotary movement of the magnetic armature (4) and to transmit the rotary movement to the valve closure member (5) for the variable control of a pressure fluid passage.
