The characteristics of Floating insulation ball valve adopts the single slope elastic sealing ring or V groove elastic sealing ring structure design, when the medium pressure is small, sealing ring and ball contact area is lesser, reason has larger sealing pressure, ensure reliable sealing medium pressure trap, sealing ring and ball contact area increases, so the sealing ring can bear larger medium thrust without damage. By ptfe sealing material has two good self-lubrication, with the sphere of the friction loss is small, so the ball long service life.
