Stainless Steel Ball Valve Importer

stainless steel
A form of steel containing chromium, resistant to tarnishing and rust
steel containing chromium that makes it resistant to corrosion
In metallurgy stainless steel, also known as inox steel or inox from French "inoxydable", is defined as a steel alloy with a minimum of 10.5 or 11% chromium content by mass. Stainless steel does not stain, corrode, or rust as easily as ordinary steel, but it is not stain-proof.
(Stainless steels) Steels that are corrosion and heat resistant and contain a minimum of 10% to 12% chromium. Other alloying elements are often present.

ball valve
A ball valve is a valve with a spherical disc, the part of the valve which controls the flow through it. The sphere has a hole, or port, through the middle so that when the port is in line with both ends of the valve, flow will occur.
(Ball Valves) Contains a slotted metal or plastic ball that aligns with the hot and cold water inlets when rotated by the faucet handle. Ball valves are reliable but tedious to fix. A metal valve is more durable than plastic under most circumstances.
any valve that checks flow by the seating of a ball
A one-way valve that is opened and closed by pressure on a ball that fits into a cup-shaped opening

importer
someone whose business involves importing goods from outside (especially from a foreign country)
The term "import" is derived from the conceptual meaning as to bring in the goods and services into the port of a country. The buyer of such goods and services is referred to an "importer" who is based in the country of import whereas the overseas based seller is referred to as an "exporter".
An importer is a software application that reads in a data file or metadata information in one format and converts it to another format via special algorithms (such as filters). An importer often is not an entire program by itself, but an extension to another program, implemented as a plug-in.
