This International Standard defines dimensions of right-angle valves that are compatible with the mounting dimensions of elbows defined in ISO 9803-1 and ISO 9803-2.
This International Standard covers right-angle valves with flanges defined in ISO 2861-1, ISO 1609 and ISO 3669. ISO 3669 lists two flange series:
-
— preferred series, and
-
— secondary series.
This International Standard covers only the valves with flanges of the secondary series.
