A gas sediment trap assembly includes a generally cylindrical length with a generally perpendicular tee and a vertically oriented capped portion. The gas sediment trap assembly is coupled to the gas supply line and the gas fired appliance. One or more gas ball valves can be coupled to the gas sediment trap assembly. The gas sediment trap assembly can be used with conventional gas piping, flexible gas piping, and/or other gas line components.

A check valve formed from a body having inlet and outlet interior chambers with the outlet chamber functioning as a diffuser when assisting in the arrest of reverse water flow. A seat base is positioned between the inlet and outlet chambers with a tubular sleeve for housing a stem having a lip positioned along one end and a threaded opposite end secured within the inlet chamber. A spring fits around the stem and a sphere is secured to the threaded end of the stem for engaging the seat base. Movement of the sphere away from the inlet chamber allows dry polymer to pass when the spring is compressed. Upon loss of force capable of moving the sphere away from the inlet chamber, relaxation of the spring allows the sphere to engage the seat base with an attached grommet before water can flow backwards into the interior chamber.

A method and apparatus for metering fluids, in particular liquid fluids, includes at least one fluid being guided out of at least one fluid reservoir through a closeable valve device in a discharge direction, at least one valve opening in the valve device being closed or opened by a valve closing member in order for the fluid to flow or be prevented from flowing through the valve opening, the opening and closing movement being performed magnetically by moving the valve closing member, which is arranged and moved in the fluid reservoir on an upstream side of the valve opening.

This valve seat is disposed below a valve ball, wherein the valve seat comprises an annular member in which a seating surface and a lower end surface of the valve ball are formed into a circular shape; a flow path is formed between the seating surface and the lower end surface, for communicating a transfer fluid including a gas and a liquid; and the flow path is formed in a predetermined shape in which a horizontal distance from the central axis which crosses the lower end surface at right angle to the inner circumferential surface of the flow path excluding the seating surface and the lower end surface is not constant over the entire circumference of the flow path.

A valve for switching of media, such as liquids or gases, is opened, closed or put into an intermediate state by at least one actuator produced from a shape memory alloy. The at least one actuator, as a function of whether electricity is applied to it, acts on at least one valve ball or a valve plunger accommodated in a core element, so that the through-flow of a medium through a fluid part below the core element, with a media-tight membrane interposed between, is opened, interrupted or partially opened in regulated or controlled manner. The core element is produced from a mechanically rigid and thermally well-conductive material, has electrical conductor tracks for electrical connection of the actuator to a supply of electricity on the top side, as well as multiple threaded through-holes for underside connection with the fluid part and the membrane and/or for top-side connection with the actuator.
