1、 Product Details:

Product model: Q347F/H/Y

Product Name: Q347 Fixed Worm Gear Ball Valve Two Part and Three Section Fixed Ball Valves, also known as Side Mounted Split Ball Valves, divide 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 flow of media. Its pivot structure ensures accurate positioning of the sphere. The standard valve seat adopts a spring structure, which pushes the valve seat 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. The company has the advantages of excellent performance, high reliability, wide applicability, and reasonable price, and is 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.
