A method and apparatus are provided for controlling a fuel delivery system to limit acidic corrosion. An exemplary control system includes a controller, at least one monitor, an output, and a remediation system. The monitor of the control system may collect and analyze data indicative of a corrosive environment in the fuel delivery system. The output of the control system may automatically warn an operator of the fueling station of the corrosive environment so that the operator can take preventative or corrective action. The remediation system of the control system may take at least one corrective action to remediate the corrosive environment in the fuel delivery system.

Ullage float assemblies for fuel tanks are disclosed including a guide member with a retaining element mounted to a valve body which includes a first valve port and a second valve port in fluid communication. Methods of preventing spillage of fuel from a fuel tank during a refueling and a diurnal fuel volumetric expansion event are also disclosed. The assemblies and methods.

A system for delivering a fluid to a fluid consuming asset having a fluid tank is disclosed. An inlet of a manifold is fluidically coupled to a storage tank that contains the fluid to be delivered. A first distal end of a fluid transporting mechanism is fluidically coupled to an outlet of the manifold. A second distal end of the fluid transporting mechanism is fluidically coupled to the fluid tank. A primary valve is fluidically coupled to the fluid transporting mechanism and restricts fluid flow to the fluid tank when fluid level in the fluid tank reaches a first fluid level threshold. A secondary valve is fluidically coupled to the fluid transporting mechanism and restricts fluid flow to the fluid tank when fluid level in the fluid tank reaches a second fluid level threshold. The first fluid level threshold is lower than the second fluid level threshold.

A flow-through pressure-vacuum valve includes a valve body having a tank-side opening and a vent-side opening. A pressure relief valve (e.g., a ball held in a corresponding seat by gravity) is positioned within a first passageway through the body. The ball is moved from the first valve seat to open the first passageway when pressure at the tank-side opening exceeds pressure at the vent-side opening by a predetermined pressure differential. A vacuum relief valve is positioned within another passageway (e.g., a serpentine passageway). The vacuum relief valve (e.g., also a ball held in a corresponding seat by gravity) is positioned within the serpentine passageway. Analogously, the ball is moved from the valve seat to open the serpentine passageway when pressure at the tank-side opening is less than the pressure at the vent-side opening by a predetermined pressure differential.

A float controlled nozzle valve for use in a fuel nozzle, to provide for gradual delivery of fuel to a fuel tank, the nozzle, having a housing, including a generally horizontally arranged spout, and embodying a float rod and float assembly, which act upon a valve provided within the nozzle housing, to detect and provide for the flow of fuel into an associated fuel tank, or to curtail the same. The float rod pivotally mounts within the nozzle housing, contains an adjustment screw, which can bias against a valve pin to determine when a valve ball is to be opened from its valve seat, to allow the passage of fuel, or when the valve ball is allowed to seat upon its valve seat, to curtail the further flow of fuel. The nozzle housing is provided for securement to the fuel tank, for which it detects the level of fuel within the tank, to determine when an additional supply of fuel is to be dispensed by way of the nozzle, into its associated fuel tank.

An overfill prevention valve that is testable to ensure proper functionality of the valve. More particularly, in one embodiment the invention is an overfill prevention valve system including an overfill prevention valve having a blocking component. The blocking component is movable between a closed position, wherein the blocking component generally blocks fluid from flowing through the valve, and an open position, wherein the blocking component generally allows fluid to flow through the valve. The valve further including a float operatively coupled to the blocking component. The system additionally has an actuator that is operable to directly or indirectly move the blocking component to at least one of its open or closed positions to thereby enable testing of the overfill prevention valve.

An aircraft engine oil filler apparatus includes a filler tube configured to be connected to an oil tank such that a bottom portion of the filler tube is disposed inside the oil tank, a valve received in the bottom portion of the filler tube movable between an open position in which the valve hydraulically connects the filler tube to the oil tank, and a closed position in which the valve hydraulically disconnects the filler tube from the oil tank, and a float disposed above the valve and operatively connected to the valve to move the valve from the open position to the closed position when oil inside the oil tank rises to a threshold level. The valve is movable independently from the float when pressure in the oil tank is greater than pressure in the filler tube. A method of operation of an oil filler apparatus is also described.

A fuel transport sensor system for precise loading and unloading of fuel for transports includes a transport computer configured to be coupled to a fuel transport having a plurality of fuel compartments. Each of a plurality of load head sensors is in operational communication with the transport computer and coupled to one of a plurality of load heads. A load arm sensor coupled to a load arm and the load arm sensors communicate with the transport computer to track which fuel compartment is being filled with what fuel type. A pair of hose sensors coupled to a delivery hose confirm the delivery hose is connecting the load head with the correct fuel type for an in-ground storage tank before allowing a fire valve of the load head to be opened.
