Overview

The dynamic ball valve adopts a single inclined elastic sealing ring or V-shaped groove elastic sealing ring structure design. When the medium pressure is too low, the contact area between the sealing ring and the ball is small, so there is a large sealing pressure ratio to ensure reliable sealing. When the medium pressure is high, the contact area between the sealing ring and the ball increases, so the sealing ring can withstand a large medium thrust without being damaged.

Hard sealed ball valve--Detailed Introduction

The floating ball valve adopts a single inclined elastic sealing ring or V-shaped groove elastic sealing ring structure design. When the medium pressure is too low, the contact area 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 high, the contact area between the sealing ring and the sphere increases, so the sealing ring can withstand a large medium thrust without being damaged. Due to the excellent self-lubricating properties of sealing ring materials such as polytetrafluoroethylene, the friction loss with the ball is small, resulting in a long service life for ball valves.
