Light-weight, versatility, and tight sealing are the benefits of using plastic valves for domestic plumbing applications. Anyway, you can't use plastic valves for applications where high temperatures are involved, so a valve made of a metal is the best choice for such applications. Ball Valve applications: Ships, oil rigs, gas plants, bioprocessing, water treatment, chlorine manufacturing, pharmaceutical, fire protection, and beverage are the common applications of this versatile valve type. So, you can understand its special capabilities here. High-pressure, high-temperature, safety, quick shut-off, and reliability are the factors that make this valve type the best type available on the market today. We can explain it to you with an example. Pipelines from an oil rig transfer liquids at high-pressure. So, you can't use an ordinary valve here. The Ball Valve that you can use for high-pressure applications such as for oil rigs should be made of a metal, and plastic is not the best material option here. Manufacturers have now introduced new features that make the Ball Valve the best option for applications mentioned above: * Valve stop: This feature prevents the lever turn more than 90 degrees. * Position indicators: These indicators show the flow direction. A useful feature for multi-port …show more content…

material Specific features Galvanized iron Sheet metal Slabs of galvanised iron are pushed into the rollers and made to pass through them Rollers made up of grey iron is mostly used for rolling process. High amount of load acting on the material which is at its recrystallization point tends to deform and then sheet metal is formed. Grey cast iron is used and it is considerably harder as it has some graphite content in its mixture which makes it hard. material Specific features iron Surface
