Product Introduction
【Product use】
Q347F type 150(Lb)~1500(Lb) fixed ball valve is suitable for chemical, petroleum, natural gas, metallurgy, and other industries, as well as long-distance natural gas pipelines containing hydrogen sulfide media, many impurities, and serious corrosion.
【Product features】
1. The valve seat adopts a spring structure to push the valve seat to the sphere, ensuring good low pressure sealing performance.
2. The front and rear valve seats of the fixed ball valve can be sealed, which is the so-called two-way sealing characteristic. Using the built-in discharge valve, the middle cavity of the valve body can be discharged outwards.
3. The pivot adopts a blow-out protection structure, bearings with low coefficient of friction, etc.It has excellent performance, high reliability and wide range of uses
