Overview

The floating insulation ball valve adopts a single inclined elastic sealing ring or V-shaped groove elastic sealing ring structure design. When the medium pressure is low, the contact surface between the sealing ring and the sphere is small, so there is a large sealing pressure ratio to ensure reliable sealing. When the medium pressure is trapped, the contact surface area between the sealing ring and the sphere increases, so the sealing ring can withstand a large medium thrust without damage. Sealing materials such as polytetrafluoroethylene have good self-lubricating properties and minimal friction with the ball, resulting in a long service life of the ball.

Product Details
