Product description
Metal seated ball valve is designed as per workingconditions or end user requirements. It is mainly applied in high pressure,high temperature, heavy corrosive and particle-containing etc harsh condition.It has trunnion mounted type and floating ball type. After pecise machining,the seat can be grinded to fit the ball. And achieve initial sealing in theaction of spring loaded.When in working conditions, the seat will contact withball more tightly under the medium pressure so as to achieve safe sealing performance,long service life and easy operation. It is widely used in poly-silicon, coalchemical, petrochemical, mining ,paper and air separation industries.
