A spindle valve for a pipe system for liquids, which valve comprises a frame (1) provided with an inlet connection (2) and at least one outlet connection (3,4) and a valve housing (5) separating the connections from each other, and a spindle (7) mounted axially slidably in the frame and provided with a valve member (8). A closing surface (3a, 6a) cooperating with the valve member is formed in the valve housing for the outlet connection (3 resp. 4) and actuating means displace the valve member between a closing position pressing against the closing surface and an opening position raised from the closing surface in order to close and to open respectively the flow path between the connections. The valve is provided with a locking device for locking the spindle axially undisplaceably at least in the closing position, in order to prevent unintentional opening of the flow path. |
