一．Product Introduction
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.
二.Product Features
- The valve seat adopts a spring structure to push the valve seat to the sphere, ensuring good low pressure sealing performance.
- 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.
- 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
