Top entry ball valves are easy to maintain, simple to disassemble, and can be serviced by simply removing the ball and seat assembly in-line.
Top entry ball valve has good sealing performance and long service life.
It can be adapted to high temperature, high pressure and corrosive substances and other working conditions to meet the needs of different industries.
Its structure is compact, easy to install and use in the environment of limited space.
Its channel is more straight, the resistance when the fluid passes through is smaller, and it can provide a larger flow rate.
