Abstract: A heated valve assembly includes a valve and a valve assembly. The valve assembly includes a valve seat extending across the flow passage and a moveable valve member movable in the flow passage relative to the valve seat between a closed position, in which the moveable valve member is sealing engaged with the valve seat to prevent flow of fluid in the flow passage past the valve assembly, and an open position in which the moveable valve member is moved out of sealing engagement with the valve seat. The valve seat includes a valve seat housing of thermally conductive material, and one or more heater elements incorporated within the valve seat housing.

Abstract: A hydraulic port assembly includes a housing having an opening therethrough; a first port located in and extending through the opening defining a flow channel through the fill port from a first end to a second end, the flow channel having an axis (A) defined between the first end and the second end and a closure mechanism moveable between an open position in which the flow channel is open and allows fluid flow therethrough and a closed position in which the flow channel is closed and prevents fluid flow therethrough.

Abstract: A flush valve comprising: a valve housing defining a fluid flow channel between an inlet end and an outlet end; a valve closure member arranged to open and close the fluid flow channel; and a mounting unit attached to the valve housing at a location intermediate the first and second ends to which the valve closure member is mounted; wherein: the valve closure member is an inflatable valve member mounted to the mounting unit such that, when in an inflated state, the valve member extends across the fluid flow channel to prevent flow of fluid past the valve member from the first end to the second end and, when in a deflated state, the valve member does not prevent flow of fluid through the fluid flow channel from the first end to the second end.

Abstract: A flush valve comprising: a valve housing defining a port; and a valve plate arranged to rotate in a plane, relative to the port, such as to vary a degree of coverage of the port by the valve plate depending on the rotational position of the plate; the flush valve further comprising: a component that rotates with the valve plate; a code formed of gradated markings provided on the component, the gradated markings formed such that a characteristic of the code varies across the component in the rotation direction; and a code reader, fixed relative to the valve housing, and positioned to read the code as it passes the code reader on rotation of the valve plate.

Abstract: A cleaning arrangement for cleaning an interior volume of a tank. The arrangement includes: a tank, the interior of which is to be cleaned, the tank having a top, a bottom, and, extending from the top to the bottom, an outer wall and an inner wall defining the interior volume. The inner wall is provided with a removable coating.

Abstract: A pressure control valve includes: a valve housing extending along an axis (A); a valve seat; a valve piston mounted within the valve housing arranged to move axially within the valve housing relative to the valve seat; a compression spring located between the valve piston and an end of the valve housing to axially bias the valve piston relative to the valve seat; and a check valve located within the valve piston.

Abstract: A rinse arrangement for cleaning an interior volume of a tank, the arrangement comprising: a tank, the interior of which is to be cleaned, the tank having a top, a bottom, and, extending from the top to the bottom, an outer wall and an inner wall defining the interior volume; and a rinse fluid inlet port mounted to an upper region of the tank, the inlet port having a first end and configured to be fluidly connected to a rinse fluid supply, in use, and a second end that extends into the tank interior; and wherein the inner wall has a convex shape from the top to the bottom, defining a convex surface (C) curving in towards the interior volume.

Abstract: A rinse device comprising rinse device comprising a housing, and where in the housing there is provided: a rinse fluid dispensing mechanism configured to eject a rinse fluid from the housing into a volume surrounding the housing; and a pressure generating mechanism configured to generate pressure waves in the volume.

Abstract: A valve heater comprising a sheet into which is integrated one or more heating elements, the sheet being shaped to be located within a valve housing. The valve may be a ball valve comprising a valve housing defining a flow conduit between an inlet and an outlet and a ball element rotatably positioned in the housing, the ball element defining a channel therethrough to form a fluid flow path through the valve in a valve open position when the channel is aligned with the flow conduit, and a valve heater located on an inner surface of the ball element that defines the channel.

Abstract: A heater assembly includes a heater assembly housing having a housing body with one or more port openings formed therethrough. The heater assembly can also include a heater element located within the housing body and shaped to form a heater loop around each of the one or more port openings.

Abstract: A rinse device comprising a housing part and a rinse hose, the housing part having a first end configured to be attached to a supply of pressurized fluid and a second end to which a first end of the rinse hose is attached, a second end of the hose is open to allow fluid to flow out of the hose, in use; the housing part defining a cavity through which pressurized fluid from the supply flows, in use, from the first end to the rinse hose, the rinse hose being a flexible and extendible hose provided with a plurality of openings through which the pressurized fluid is ejected; and wherein the rinse hose comprises an elongate tube through which the fluid flows, in use, the openings provided through the elongate tube.

Abstract: A fill port assembly comprising: a housing having an opening therethrough; a fill port located in and extending through the opening defining a flow channel through the fill port from a first end to a second end, the flow channel having an axis defined between the first end and the second end; and a closure mechanism moveable between an open position in which the flow channel is open and allows fluid flow therethrough and a closed position in which the flow channel is closed and prevents fluid flow therethrough, wherein the closure mechanism comprises: a ball located in the flow channel, the ball having a passage therethrough, the ball being rotatable within the flow channel such that in the open position, the passage is aligned with the flow channel and in the closed position, the passage is not aligned with the flow channel.

Abstract: A fill port assembly comprising: a housing having an opening therethrough; a fill port located in and extending through the opening defining a flow passage through the fill port from a first end to a second end, the flow passage having an axis defined between the first end and the second end; and a closure mechanism moveable between an open position in which the flow channel is open and allows fluid flow therethrough and a closed position in which the flow channel is closed and prevents fluid flow therethrough, wherein the closure mechanism comprises: a cap attached at a first side of the cap to a first side of the housing via a hinge, the cap pivotable about the hinge between an open position with respect to the fill port and a closed position to close the second end of the fill port.
