Short description
1.1 This specification covers self-contained automatic shut-off valves (also known as excess flow valves) for air or nitrogen service. They are intended to be installed as safety devices to quickly and automatically shut off flow under certain excess flow conditions caused by a downstream failure or casualty, such as a hose rupture. 1.2 The values stated in this specification in inch-pound units are to be regarded as the standard. The SI equivalents shown in parentheses are provided for information only.
