Metal seated ball valves are widely used in chemical, petroleum, natural gas, pharmaceutical, metallurgical and other industries. Their advantages include reliable sealing, long service life, high temperature resistance, and corrosion resistance. They are particularly suitable for piping systems with high temperature and high pressure, corrosive media, and media prone to scaling.
Features & Benefits
a) Unique, the metal seated ball valve with patented single-seat ball valve design. It has a flat spring set acting through a hard-faced bearing against the bottom ball shaft which provides sufficient initial ball-seat load for valve tightness, even at low delta P.
b) Metal seated ball valve proven in qualification tests and field operation to be solids–proof, even for the toughest applications on slurry service with solids particles.
c) Tightness rates: Allowable leakage rate at full Delta P: ASME/ FCI 70-2 Class VI/V. Tighter shutoff available upon request.
The leakage rate also can be customization from end-user request
d) The metal seated ball valve with standard extension bonnet/stem, whose design base on the different temperature range.
e) Uni-directional or bi-directional sealing
