Ball Valve suppliers Overview The Top Entry Ball Valve closes tightly with only 90 degrees of rotation and small torque. The perfectly equal inner cavity provides a low resistance, straight flow path for the medium. It is larger in size and made of better materials than the typical household valve. The surface is painted for a good finish. Top Entry Ball Valves are suitable for conveying gases such as air, vacuum, liquids such as water, organic solvents and liquids containing suspended particles. The Top Entry Ball Valve is simple in structure, small in size, quick to open and close, and easy to operate. It has the lowest flow resistance and does not interfere with the transmission of the medium. In addition, it can be reliably used in corrosive media and low boiling point liquids as it does not jam during operation. Moreover, a complete seal can be achieved over a wide range of pressures and temperatures.
