Working principle of stainless steel flange ball valve

The closing element of a stainless steel flange ball valve is a ball, which rotates around the centerline of the valve body to achieve opening and closing. Ball valves are mainly used in pipelines to cut off, distribute, and change the flow direction of the medium. The floating ball valve adopts a specially designed double inclined elastic sealing ring, which effectively reduces the friction between the ball and the sealing ring, and reduces the operating torque. When the medium pressure is low, the contact area between the sealing ring and the sphere is small, so there is a larger sealing pressure ratio to ensure reliable sealing. When the medium pressure is high, the contact area between the sealing ring and the ductile iron also increases accordingly. Therefore, the sealing ring can withstand large medium thrust without damage, ensuring reliable sealing.
