Ball Valve Application Areas
Ball valve is normally using rubber, nylon and PTFE as its seat sealing materials, therefor, the applicable temperature is limited by the materials. The switching process is reliazed by pressing ball under pressure of media, this is called floating ball ball valve, the seal seat will be deformed under this pressure, and this will ensure seal tightly.
In addition, seat normall made of plastic, it should consider that the heat resistance and fire protection are appropriate when selecting of valve, especially in the fields of petroleum
Prtrochemical, metallurgy and other industries. it must pay more attention on the equipments or pipline with Inflammable, explosive media.
Gernally, with the advantages of double position adjustment, strict seal performance, abrasive-resistance, or requiring of switch fastly, also in the condition of high pressure, low noise, Air pockets and gasification phenomenon, or requiring of low torque, low pressure loss, Ball valve is recommended.
- Ball valve also suitable for simple structure, low pressure environment, and pipe network with corrosive media.
- In low temperature equipment and pipeline, ball valve could also be used.
- While in the Oxygen pipe network, it needs ball valve to be degreased.
- In oil or gas transportation main pipeline fields, Ball valve will be full bore and welding connection.
- When requiring of adjusting feature, V type ball valve will be used.
- For temperature higher than 200℃, it could use metal seal ball valve.
