Ball type of ball valve

Question: What type of ball does \"trun MTD ball\" refer to in the structure classification of ball valves, and what is the difference between it and a float ball? Thank you! !
"“trun MTD ball” may refer to “trunnion mounted ball”, that is, a ball-type structure supported by trunnions. In ball valves with this structure, the sphere is supported by bearings at both ends, making them suitable for use in high-pressure applications; since the pressure of the medium is very high, the sphere does not move as a result of that pressure. The “float ball” refers to a floating ball structure; the ball is not fixed and can undergo slight displacement (floating) inside the valve body under the influence of the medium pressure. Floating ball valves are generally used in low-pressure applications, as the ball is directly subjected to the pressure of the medium, making them suitable for small-diameter and low-pressure scenarios. .
It refers to fixed balls and floating balls
