There is provided a system separator having a backflow preventer including a housing enclosing a main flow conduit, a valve seat inside the housing on the main flow conduit, and a valve body movable relative to the valve seat to close off the main flow conduit together with the valve seat in a closed position and to release the main flow conduit in an open position. The valve body is alternately movable between the closed position and the open position by at least one of a pressure difference in the main flow conduit or a force of a spring element, and the main flow conduit is divided in the area of the valve body into at least one outer flow conduit and one inner flow conduit, and the valve body encloses the inner flow conduit and forms at least one valve-body valve seat on the inner flow conduit.

Nozzle for water, in particular for a water cannon
A full jet nozzle for use with a water cannon, the nozzle having a body that encloses a flow channel running along an axial direction, having an outlet opening provided at an axial end of the flow channel, which has an external circumference which encloses an outlet surface to form a flow cross-section. The flow cross-section has a substantially circular or annular base area. There is at least one radial cross-sectional extension of the outlet area is provided exclusively in an angular range of the outer circumference of a maximum of 180°. The full jet nozzle also has at least one radial cross-sectional extension formed by a slot running with its longitudinal axis parallel to the axial direction, which opens perpendicular to the base area or has a recess running with its longitudinal axis parallel to the axial direction, which opens perpendicular to the base area.

FIRE-EXTINGUISHING FITTING AND FIRE-EXTINGUISHING COUPLING HAVING A SOLID WETTING AGENT HOLDER
The invention relates to a fire-extinguishing fitting, in particular in the form of a nozzle, comprising at least one water inlet end and at least one water outlet end, which are or can be connected to each other by means of a water passage in such a way that extinguishing water is conducted; wherein a component for controlling or changing an extinguishing-water flow flowing from the at least one water inlet end to the at least one water outlet end is provided in the water passage. The fire-extinguishing fitting according to the invention is characterized in that a solid wetting agent holder is inserted in the water inlet end and/or the water outlet end in such a way that the solid wetting agent holder can be removed through the water inlet end or the water outlet end, which solid wetting agent holder has an insert, around which extinguishing water can flow and which has an inner accommodating space for accommodating a solid wetting agent.
The invention relates to a firefighting fitting (10) with aluminium components (12). The aluminium components are provided on the surface thereof with an anodized coating (110) having pores (120). The anodized coating is a combined porous polymer-metal oxide layer. Colourants (130) are incorporated in the pores of the anodized coating. The anodized coating has a duplex-compacted layer (140, 150). The invention also relates to a method for coating aluminium components of a firefighting fitting.
