Stainless Steel Flanged Ball Valves

stainless steel
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.
A form of steel containing chromium, resistant to tarnishing and rust
steel containing chromium that makes it resistant to corrosion
(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 valves
(ball valve) any valve that checks flow by the seating of a ball
(Ball Valve) A simple non-return valve consisting of a ball resting on a cylindrical seat within a liquid passageway.
(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.
A one-way valve that is opened and closed by pressure on a ball that fits into a cup-shaped opening

flanged
A flange is an external or internal rib, or rim (lip), for strength, as the flange of an iron beam or I-beam (or a T-beam); or for a guide, as the flange of a train wheel; or for attachment to another object, as the flange on the end of a pipe, steam cylinder, etc.
(Flangs) The part of a window that surrounds the frame; for mounting in place and installation.
A hollow forging with one or more protruding ?ribs? or flanges on the outside diameter.
