Abstract (en)
[origin: EP0669504A1] The connector has a socket (1) grouted into the wall (2) and with access cover (3). An inlet (6, 7) and a return (7) pipe end inside the socket.A valve (12, 13) with plug (18) is connected by a first union (8, 9) to each pipe end, and opens to allow the flow of liquid when a pipe (25) to the radiator is connected to a second union (15, 17) at right angles to the first. A passage (29) connecting the first valves contains a plug (30) operated from the outside and which is movable into any position between fully opening the passage or shutting it off completely, thus allowing use with a single- or twin-pipe system.
