Overview
Product Introduction: Two point and three section fixed ball valves, also known as measuring and installing split ball valves, divide the valve body into asymmetric left and right halves along a section perpendicular to the valve channel axis. They are mainly used in pipelines to cut off, distribute, and change the direction of medium flow. Its pivot structure ensures accurate positioning of the sphere.
Product Details
Product Structure and Usage
Two-part and three-stagetrunnion mounted ball valveAlso known as the split type ball valve, it divides the valve body into asymmetric left and right halves along a section perpendicular to the valve channel axis. It is mainly used in pipelines to cut off, distribute, and change the direction of medium flow. Its pivot structure ensures accurate positioning of the sphere. The standard valve seat adopts a spring structure, which pushes the valve cover towards the sphere, ensuring good low-pressure sealing performance. The ball valve has a bi-directional sealing feature, where both the front and rear valve seats can be sealed. With the built-in discharge valve, the valve body cavity can be discharged outward. The pivot adopts anti blowout protection structure, low friction coefficient bearings, etc. It has the advantages of excellent performance, high reliability, wide applicability, and reasonable price.
Suitable for industries such as chemical, petroleum, natural gas, metallurgy, as well as natural gas long-distance pipelines containing hydrogen sulfide media, high impurities, and severe corrosion.
