Abstract

The control valve has a valve body (3) made of metal and defining an inlet port (4) and two outlet ports (5, 6). A valve member (7) is movable by a valve spindle (15) between a first end position against a valve seat (9) and a second end position against a valve seat (8). The valve spindle (15) is rotated by a control and drive unit (2) including an electric motor (17). The motor (17) is housed within a casing of plastics material comprising a moulded base member (18) and a removable cover (19). The base member (18) has fixed and/or supporting means for components of the control and drive unit (2). The base member (18) is supported on three spaced pillars (10, 11, 12) extending from the valve body (3). As the base member (18) is made of plastics material it insulates the unit (2) from the valve body (3). Furthermore, the pillars (10, 11, 12) do not project into the casing and thus they do not provide a path for heat through the base member (18). <IMAGE>
