A fuel filter is provided which comprises a manifold, a connector element, a filter bowl, a filter element, an inlet shutoff valve, an outlet shutoff valve, an inlet port, an inlet passage, an outlet port, an outlet passage and a relief valve in which the connector element is fixed to the manifold, and the filter bowl is reversibly fixed to the connector element. The filter bowl is adapted to reversibly receive the filter element and is so configured that when the filter element is located within the filter bowl and the filter bowl attached to the connection element the filter element divides the space defined by the connector element and filter bowl into an inlet filter chamber and an outlet filter chamber. The inlet port mouths through a surface of the manifold, and the inlet port and inlet filter chamber are in fluid communication via the inlet passage.

A filter element includes a first end cap, a second end cap, and a ring of filter media disposed between the first end cap and the second end cap. The ring of filter media circumscribes a central cavity. The filter element also includes an air-bleed conduit axially extending through the central cavity. The air-bleed conduit includes a first portion integrally formed with the first end cap and a second portion integrally formed with the second end cap. The second portion is configured to fluidly connect to the first portion.

A discharge control device for a filter system and a filter system for filtering a media flow of a first and a second medium is provided with a collecting chamber that collects the second medium separated from the media flow. A sensor arrangement with a first sensor unit, a second sensor unit, a first shut-off valve having a closure body, and a second shut-off valve is provided. The first sensor unit is operatively connected to the first shut-off valve. The first sensor unit has a float that purely mechanically actuates the closure body of the first shut-off valve. The second shut-off valve is arranged in series in flow communication with the first shut-off valve. The second shut-off valve has an electromagnetically actuatable valve controlled by the second sensor unit as a function of a fill level of second medium in the collecting chamber.

A filter arrangement for an aquarium is disclosed. The filter arrangement can include a housing assembly, a pump assembly, a transfer tube assembly, and a valve assembly for controlling water flow through the transfer tube assembly. The transfer tube assembly can include a tube structure within which a valve body of the valve assembly is rotatably disposed. The tube structure can be formed from a first tube half mated to a second tube half to permanently secure the valve body within the tube structure. A valve operator can be connected to the valve body to advantageously allow a user to manipulate the flow of water through the transfer tube assembly. Control of water flow through the filter arrangement is beneficial for obtaining a desired water flow for a certain aquarium size and application and for reducing flow during certain periods, such as during feeding.

A fuel storage and supply arrangement serves as a source of fuel to be dispensed via at least one fuel dispenser in a fuel dispensing environment. The arrangement comprises a storage tank for containing a quantity of the fuel, fuel piping configured to convey fuel from the fuel storage tank to a fuel dispenser, and a fuel conditioning and filtration assembly having an inlet in fluid communication with the fuel piping and an outlet in fluid communication with the fuel storage tank to return the fuel. A fuel conditioning and filtration element is interposed between the inlet and the outlet, the fuel conditioning and filtration element being configured to remove water from the fuel passing through the filter element. A flow valve allows and prevents flow of fuel through the filter element. Processing circuitry is operative to control the flow valve based on predetermined criteria.
