ball valve

it is a shut off valve that controls the flow of a liquid or gas by means of a rotary ball having a bore. By rotating the ball a quarter turn (90 degrees) around its axis, the medium can flow through or is blocked. They are characterized by a long service life and provide a reliable sealing over the life span. even when the valve is not in use for a long time. As a result, they are more popular as a shut off valve then for example the gate valve. CS ball valves is a kind of ball valve that is formed by pouring liquids into a mold and then allowing them to solidify. Alloy steel is the most common casting material. Cast steel is divided into cast carbon steel, cast low alloy steel and cast special steel. Cast steel refers to a steel casting produced by a casting method. Cast steel is mainly used to make parts that are complex in shape, difficult to forge or cut, and require high strength and plasticity. They are available in three-piece construction. It offers full flow with minimum turbulence and can balance or throttle fluids. Ball move from closed to full open in a quarter of a turn of the shaft and therefore referred to as quarter-turn ball valve.

Flanged

Flanged ball valves are characterized by their connection type. The ports are connected to a piping system via flanges that are usually designed in accordance with a certain standard. These valves provide a high flow rate since they typically have a full-bore design. When choosing a flanged ball valve, besides the pressure rating, you also have to check the flange compression class which indicates the highest pressure this connection type can withstand. These ball valves are designed with two, three or four ports, they can be approved for specific media, have an ISO-top and everything else a standard quarter turn valve could have. They are typically made out of stainless steel, steel, or cast iron. For different types of ball valves, click here.
