API Standard B367 Gr.C-2 Worm Gear Operated Metal Seated Ball Valve

The ball of a floating ball valve is floating, and under the pressure of the medium, the ball can produce a certain displacement and tightly press on the sealing surface of the outlet end, ensuring the sealing of the outlet end. The floating ball valve has a simple structure and good sealing performance, but the ball bears all the load of the working medium and is transmitted to the outlet sealing ring. Therefore, it is necessary to consider whether the sealing ring material can withstand the working load of the ball medium. When subjected to high pressure impact, the ball may deviate. This structure is generally used for medium and low pressure ball valves.

The main characteristics of a ball valve are its compact structure, reliable sealing, simple structure, convenient maintenance, and the sealing surface and spherical surface are often in a closed state, which is not easily eroded by the medium. It is easy to operate and maintain, suitable for general working media such as water, solvents, acids, and natural gas, and also suitable for harsh working conditions such as oxygen, hydrogen peroxide, methane, and ethylene. It has been widely used in various industries. The valve body of a ball valve can be integral or modular.

1. The flow resistance of a ball valve is small. When the full diameter ball valve is opened, the ball channel, valve body channel, and connecting pipe diameter are equal and form a diameter, and the medium can flow almost without any loss.

2. The ball valve can be fully closed and fully opened by rotating 90 °, with quick opening and closing. Compared with gate and globe valves of the same specifications, ball valves have a smaller volume and lighter weight, making them easier to install in pipelines.

3. Advanced valve seat: The valve seat is designed based on years of experience in ball valve manufacturing, ensuring valve sealing, low friction coefficient, small operating torque, multiple valve seat materials, and a wide range of applications.

4. An error free switch handle: using a flat head valve stem, the connection with the handle will not be misaligned, ensuring that the switch status indicated by the handle is consistent with that of the valve.

5. Locking device: To prevent missoperation of valve opening and closing, there are locking holes in the fully open and fully closed positions of the valve to ensure that it is in the correct position.

6. Valve stem anti flying structure: The valve stem is bottom mounted to prevent pressure from flying out. At the same time, it can form metal contact with the valve body after a fire, ensuring that the valve stem is sealed.
