pipeline ball valve

A pipeline ball valve is a ball valve assembly which can be made sufficiently large and robust to be installed in a pipeline, particularly an undersea oil pipeline. The diameter of the pipeline ball valve is DN15~800 mm. The size of the pipeline ball valve is from NPS 6" to 56". The pipeline ball valve is ideal for the medium such as natural gas, liquefied gas, petroleum and so on. As for the pressure, it is applicable for 150Lb~1500Lb. the applicable temperature for the pipeline ball valve ranges from -28°C to 150°C. Besides, the pipeline ball valve complies with the following standards. The design and manufacture standard is API 608. The test standard of the pipeline ball valve is API 598. The end connection standard and the face-to face standard are separately ASME B16.5 and ASME B16.10. The pipeline ball valve can operate by turbo transmission, pneumatic, electric, gas and liquid linkage.

The pipeline ball valve is a ball valve with a fission, full-bore, two-way seal, float type seal, fire prevention and anti-static device. The pipeline ball valve consists of body, bonnet, ball, stem, seat and sealing. The main body materials of the pipeline ball valve are ASTM A216 WCB, ASTM A351 CF8 and CF8M. Furthermore, the internal components of the pipeline ball valve are all nickel-plated on surface or made of the material 316, and the seal ring is made of the special polymeric material. Therefore, the pipeline ball valve not only features by favorable anti-corrosion and sulfide-resistance capacity. The fine fire-proofing, static-prevention and sealing performance are also enjoyed by it. With wide range of suitable pressure and temperature, the valve features by both all-diameter types and crinkled-diameter ones with diversified applicable driving units. It is a kind of ideal choice in chemical industry, petroleum refining industry, mining and conveying system of natural gas etc.
