FLOAT VALVE WITH RESETTABLE AUTO-FILL

摘要

A float valve can include a selection mechanism having an open configuration in which flow into and out of the valve is permitted, and a closed configuration in which flow out of the valve is permitted and flow into the valve is prevented. The selection mechanism can be actuated from the closed configuration to the open configuration. A method of actuating a float valve can include actuating the valve from a closed configuration in which flow into the valve is prevented but flow out of the valve is permitted, to an open configuration in which flow into and out of the valve is permitted. The valve can actuate from the open configuration to the closed configuration, and from the closed to the open configuration, in response to a flow rate through the valve being greater than a predetermined level.
