The ball of the fixed ball valve is fixed by the lower valve stem, and does not move after being pressed. Therefore, in the design, the two sealing rings must have sufficient pre-tightening force to ensure the sealing of the valve seat and the ball, which is a double-sided forced seal. Thrust or plain bearings are usually mounted on the upper and lower valve stems that are integral with the ball.
