A thermostatic valve for a coolant circuit of an internal combustion engine, with a housing through which the flow is capable of passing and which has a first throughflow orifice for connection to a first coolant line, a second throughflow orifice for connection to a second coolant line, and a third throughflow orifice for connection to a third coolant line, and with a closure member which is mounted in the housing and which can be adjusted by an actuating unit, the closure member having a first shut-off element for shutting off the first throughflow orifice and a second shut-off element, coupled to the first shut-off element, for shutting off the second throughflow orifice. The second shut-off element is assigned an adjusting device, via which the second shut-off element can be adjusted relative to the first shut-off element in such a way that the closure member can be brought, on one hand, into a passage position in which it can close exactly one throughflow orifice, and, on another hand, into a shut-off position, in which it can close two throughflow orifices.
