Product Description

DN300 Carbon Steel Turbine Flange Fixed Ball Balve

 

Application:

 

Two-part and three-part fixed ball valves are also called test-fit split ball valves. The valve body is divided into asymmetrical left and right halves along a section perpendicular to the axis of the valve channel. It is mainly used for cutting off, distributing and changing the pipeline. The flow direction of the medium. Its pivot structure ensures accurate ball position. The standard valve seat adopts a spring structure to push the valve cover to the sphere, ensuring a good low-pressure sealing performance. The valve seat of the ball valve can be sealed before and after the valve, that is, the so-called two-way sealing feature. Using the built-in discharge valve, the cavity of the valve body can be discharged outward. The pivot adopts an anti-blowout protection structure, bearings with low friction coefficient, etc. It has the advantages of excellent performance, high reliability, wide range of uses, and reasonable price.

 

Electric fixed ball valve is suitable for chemical, petroleum, natural gas, metallurgy, and other industries and long-distance natural gas pipelines containing hydrogen sulfide media, many impurities, and serious corrosion.

 

Features:

 

Q347F flanged fixed ball valve, also known as test-mounted split ball valve, divides the valve body into asymmetrical left and right halves along the section perpendicular to the axis of the valve channel. It is mainly used to cut off, distribute and change the direction of medium flow in the pipeline. . Its pivot structure ensures accurate ball position
