Special seat design
The floating ball valve adopts the design of flexible seal ring structure .when the medium pressure is lower ,the contact area of seal ring and ball is smaller .So higher sealing ratio is formed at the place where the seal ring and ball contact to ensure reliable sealing .When the medium pressure is higher ,the contact area of seal ring and ball becomes bigger along with the elastic deformation of seal ring ,so the seal ring can ensure higher medium thrust without being damaged .
Anti-static structure
The ball valves is provided with the anti-static structure and adopts the static electricity discharge device today directly form a static channel between the ball and body through the stem ,so as to discharge the static electricity produced due today friction during the opening and closing of ball seat through the pipeline ,avoiding fire or explosion that may before cause static spark and ensuring system safety .
