Abstract
A fluid shutoff apparatus utilizes a float [] of a float chamber [] connected to a float-operated valve [] to provide positive shutoff of fluid to a downstream load upon excessive flow from the fluid outlet [] of the apparatus. The float-operated valve is shut when fluid discharge from the apparatus is greater than the flow rate from a flow-limiting valve [] connected to a fluid inlet [], decreasing the fluid level in the float chamber. The volume of the float chamber prevents inadvertent shutoff of fluid due to normal perturbations in flow to the load.
