Shut-off angle union for the return connection of radiators in two-pipe and one-pipe heating systems. The angle pattern is suitable for radiators with a side connection, where the pipework comes from the wall or floor perpendicular to the radiator’s vertical axis.

The union allows the maximum flow through the radiator to be preset — a key function for hydraulic balancing of the system. The built-in shut-off function makes it possible to isolate an individual radiator at any time without having to interfere with the other radiators or drain the entire heating system. The integrated drain cock facilitates radiator removal and servicing with minimal water leakage. The body is made of brass with a nickel-plated surface resistant to moisture.
