FIELD: machine building. ^ SUBSTANCE: universal case (100) of valve consists of functionally interconnected first, second, third and fourth channels (102, 106, 108, 104) for fluid medium with sections equipped with internal thread. Gate (200, 300) can be installed in the channel chosen from the above mentioned. The fourth channel (104) is positioned at angle to the first and the second channels. A unit of a cover corresponding to a concrete type of the valve controlling fluid medium flow can be installed in third channel (108). The valve can be of a ball, or angular type, or it can be a valve installed on a reservoir. When the gate is installed into the fourth channel, first and second valves (102, 106) have common axis and correspond to the first configuration, i.e, to configuration of a ball valve wherein the flow of fluid medium runs along the first trajectory (302) between said channels (102, 106). When gate (200) is installed in the first channel, second and fourth channels (106, 104) facilitate the second configuration corresponding to an angular valve with second nonlinear trajectory (202) of fluid medium. The flow of fluid medium via the valve case is controlled by change of cross section of a channel for first or second trajectory (302, 202) of fluid medium. ^ EFFECT: expanded functionality of valve cases. ^ 6 cl, 4 dwg |
