Abstract
A sectional valve includes a working valve and a control valve, which controls the working valve. In order to permit a greater flexibility with respect to possible settings and/or use or operation by comparison to known solutions, it is proposed, for example, that the control valve have a control spring (34, 34′), which presses the anchor (5) onto the control valve seat (17), and against which the control coil (26) lifts the anchor (5) from the control valve seat (17), a permanent magnet (29), which in an actuation state is configured to hold the anchor (5) lifted from the control valve seat (17) by the core (35), and a magnet holder (28), in and/or on which the permanent magnet (29) is held in the actuation state, and which permits a distance from the permanent magnet (29), and/or that the control valve is configured to variably position the core (35) along a force generated by the control spring (34, 34′).
