The ball can maintain pressure sealing of pipeline when it is closed or fully opened.Shorter upper sleeve reduces bearing load and operation torquelimit device ensures the accurate opening and closing position of the valvethe ball and stem are separated so as to reduce stem load. The stem adopts anti-blow-out design.The sealing surface is inserted into te metal seat by polymer or plasticthe metal backed self-lubricating ptfe bearing and ptfe thrust washersreduce the opening torque and prolong the service life of the valve. Stem leakage can be prevented through the emergency grease fitting. Nickel and phosphor treatment to the parts can enhance the anticorrosive performance.The fireproof design of metal wound gasket of stainless steel and graphite can prevent external leakage.Anti-static designtrunnion typefull borereduced borebolted coverwelded coverturn 90 degree opening or closedetachable seat ptferptfeend: rf, bw, swapplicable temperature: -196-540supply air: 1bar to 8bar.
