Top Entry Ball Valve
Top Entry Ball Valve Description
The Top Entry Ball Valve is a highly efficient valve that provides an exceptional sealing performance with only a 90-degree rotation and minimal torque. It is designed with a perfectly equal inner cavity, ensuring a low resistance and straight flow path for the medium. The valve is larger in size and crafted from superior materials compared to typical household valves, with its surface coated for a sleek finish.
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.
