Pipeline Ball Valve

Using a corrosion resistant designing and low coefficient of friction bearings, even under the effects of high pressure pipeline, can also minimized torque to facilitate the valve switching. Bi-directional sealing performance of inlet and the outlet valve seat. When the pipeline in accident, fire the valves and valve seats inside burned or damaged, under the force of spring metal seat automatically closely aligns to the ball, that only a small leak between the valve seat and ball, will effectively prevent the fire spread. The unique design of anti-static device, effectively prevent the discharge phenomenon, and built-in anti-blow-out stem design, effectively prevent stem ejected. When the valve is an accident of emergency, first, valve will closed, then sealant injected device inject into sealant to sealing against the valve seat and ball. In the normal times can be used to increase lubricant.
