The valve (1), for instance, for heating system, with housing (2) with input connection (3) and the outlet connection (4). And at the way (5) of the flow between those connections (3,4) there is installed a shutoff node with valve element (6) and the seat node (7). Such a valve can be used irrespectively of the direction of flow. The seat node has two outlets (17) of the seat, to one of those there is connected the input connection (3), and to the other one - the outlet connection (4); at that the valve element (6) and the seat node can move one with respect to another in such a way that the valve element (6), on choice, interacts with one oranother outlet (17) of the seat of the valve. |
