1. Structure. The ball of the side-mounted ball valve is installed on the side of the valve body, and the ball of the top-mounted ball valve is connected to the valve cover through the valve stem.
2. Sealing method. Side-mounted ball valves usually use soft seals or metal seals, while top-mounted ball valves use elastic seals or metal seals.
3. Installation method. The side-mounted ball valve is easy to install and occupies a small space. It is suitable for occasions with narrow space, curved and complex pipelines; the top-mounted ball valve is relatively large in size and requires more space for installation. It is suitable for pipelines with higher requirements.
4. Applicable occasions. The side-mounted ball valve is suitable for occasions with narrow space, curved and complex pipelines, such as chemical, metallurgical, electric power and other fields; the top-mounted ball valve is suitable for pipelines with higher requirements, such as high temperature, high pressure, etc.
