The forged steel fixed ball valve can be designed in one-piece and three-piece type, with two floating valve seats that can be moved under the pressure of the medium. A specific spring is equipped on the bottom of the valve seat to ensure that the two valve seats can be close to the ball. Under the action of the medium pressure, the ball is pushed closer to the valve seat to ensure sealing.
The fixed ball valve is equipped with a movable seat sealing ring. The sealing ring will be displaced under the pressure of the medium. Only the medium pressure exists, and the pressure will push the seat sealing ring close to the ball to ensure the sealing effect.
