Patent abstract
A valve assembly includes an automatic excess flow shut-off mechanism for preventing excess flow between an inlet and an outlet of the assembly. The excess flow shut-off mechanism is adapted to automatically stop fluid flow through the valve assembly when the flow exceeds a specified flow rate. The excess flow shut-off mechanism prevents flow when it's set and allows flow when it's reset. The valve assembly also includes a manual set mechanism for setting the excess flow shut-off mechanism even when there is no excess flow. The valve assembly additionally includes a manual reset mechanism for resetting the shut-off mechanism and for allowing excess flow.
