The invention relates to a valve or water shut-off device for controlling a heating system for a motor vehicle. Sliders of limited volume and area are provided therein for sealing off different channels, which sliders sit on a central support element (8). By this means, when plastics are used as the material for the housing (1) and sliders (9; 10), it is possible to achieve lower frictional forces. |
