Trunnion mounted ball valve is a fixed ball valve, which is different from floating type in working principle.
Floating ball valve has only one upper valve stem and no lower valve stem. When the valve is closed, the fluid will push the valve ball, and the valve ball will produce a certain displacement in the direction of fluid force. In this way, the valve ball will be squeezed on the valve seat, and a seal will be formed between the ball and the valve seat. This belongs to one-sided seal, also known as rear valve seal. It can be called ball valve seat immobility.
When the valve diameter increases and the weight of the valve ball increases, the floating ball is easy to squeeze and deform the valve seat and increase the torque. With the fixed ball valve structure, the lower valve stem can be used to jack up the ball and reduce the burden of the valve seat. The working principle of the fixed ball is that when the valve ball is closed, because the upper and lower valve rods fix the position of the ball, the ball does not move, and the valve seat closes the valve under the preload of the spring to achieve sealing. It belongs to bilateral sealing, that is, the valve seats on both sides play the role of sealing.
In addition, there are more applications of fixed ball under high pressure, but the structure of fixed ball is more complex. Floating ball is more cost-effective under the condition of small diameter, medium and low pressure.
