The present invention relates broadly and separately to a flow control valve and a float control valve assembly for use in the refilling of storage vessels, particularly fuel tanks. The invention also relates generally to a vessel overfill protection system. The flow control valve comprises a valve body defining a fluid passageway disposed between a fluid inlet and a fluid outlet and a piston assembly located at least in part within the fluid passageway. The piston assembly includes a piston support to which a piston is slidably mounted for opening and closure of the fluid outlet. The piston support includes at least one fluid sampling passage arranged to provide pressurised fluid from the fluid inlet to an upstream surface of the piston which is urged for opening of the fluid outlet to permit flow of fluid through the fluid passageway. The float control valve assembly includes a float assembly body adapted to mount within a vessel to be filled with fluid via the flow control valve. The float control valve includes a pilot valve and a pilot control passage in fluid communication with the flow control valve. The pilot valve is operatively coupled to a float member for closure of the pilot control passage on flooding of the float housing to promote closure of the flow control valve.

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. One or more sensors may be employed to signal proper operation of the remediation system.

Systems are provided for a noise attenuation device for a valve. In one example, a system may include a single noise attenuation device located below a base of a fill limit vent valve.

Block storage element and method for supplying liquid to a block storage element. The block storage clement has an overflow and the method includes introducing the liquid into an overflow distributor with a distributor limit. The liquid is throttled by at least one passageway arranged in the distributor limit and gets into a tub area of the block storage element, and the liquid that is not drained by way of the at least one passageway is discharged via. the overflow.

A water shut-off device is disclosed. The water shut-off device has an inlet port and an outlet port. The water shut-off device includes: a housing fluidly connected to the inlet port and the outlet port, the housing having an opening at its upper end and including: a valve for switching the device between an open configuration and a closed configuration, the valve permitting flow of water through the device in the open configuration and prohibiting flow of water through the device in the closed configuration; a gear wheel secured to the housing and operatively coupled to the valve, the valve being actuated by rotations of the gear wheel; and an anchor in mechanical communication with the gear wheel, the anchor including: a container for receiving water flowing through the opening; and at least one pallet connected to the container, the at least one pallet being configured to catch against one or more teeth of the gear wheel, the anchor being rotatably mounted at a fixed pivot in the housing such that the anchor swings about the pivot as water collects in the container, the swinging of the anchor about the pivot causing the at least one pallet to alternately catch and release a tooth of the gear wheel, thereby causing the gear wheel to rotate in a first direction.

A non-pressure valve is provided, and includes a tubular housing having an inlet and an outlet, and a flow-through support mount disposed in the outlet. The non-pressure valve also includes a poppet slideably coupled with the flow-through support mount and extending towards the inlet, and an outlet fitting extending through the flow-through support mount and the first poppet, the outlet fitting forming a slide guide for first poppet. The non-pressure valve also includes a sliding bell disposed around a portion of the first poppet and configured to slide independently of the first poppet. The non-pressure valve functions to divert a portion of the fuel flow through a hose to the remote fuel vent.
