Features Of Lined Ball Valve

1. Among all valves,Lined Ball Valve offer the lowest flow resistance. When a full-bore ball valve is open, the ball and body passages, as well as the connecting pipes, are of equal diameter, allowing for virtually lossless flow.
2. A ball valve can be fully opened or closed with a 90° rotation, enabling rapid opening and closing. Compared to gate and globe valves of the same specification, ball valves are smaller and lighter, making them easier to install in pipelines.
1. Advanced Valve Seat: Designed with years of experience in ball valve manufacturing, the valve seat ensures a tight seal, low friction, and minimal operating torque. A variety of seat materials are available, allowing for a wide range of applications.
2. Reliable Opening and Closing Handle: The flat-headed valve stem ensures a secure connection to the handle, ensuring that the handle indicates the correct opening and closing state.
3. Locking Device: To prevent accidental opening and closing of the valve, locking holes are provided in the fully open and fully closed positions to ensure the valve is in the correct position.
4. Stem Flyaway Prevention: The stem is bottom-mounted to prevent it from flying out under pressure. It also provides metal-to-metal contact with the valve body in the event of a fire, ensuring a tight seal. 5. A ball valve uses a sphere with a circular through-hole as the opening and closing element. Driven by the valve stem, the sphere rotates 0 to 90 degrees around the center of the stem to complete the opening and closing function. It features a compact structure and quick opening and closing. A 90-degree rotation closes the valve, shutting off the pipeline medium. The ball passage diameter is the same as the pipeline diameter, providing low flow resistance and high flow capacity. The valve stem is bottom-mounted, eliminating the risk of stem protrusion and ensuring safe operation.
