China CF8 PN16 Floating Ball Valve Suppliers | High-Quality Factory Sealed Valve Solutions
Product Feature
1. Among various valves, ball valves have the least flow resistance. When a full-bore ball valve is fully open, the diameter of the ball passage, the valve body passage, and the connecting pipe diameter are equal and form a straight line. The medium can flow through almost without any loss.
2. A ball valve can be fully opened or closed by rotating 90 degrees, and it operates quickly. Compared with gate valves and globe valves of the same specification, ball valves are smaller in size and lighter in weight, making them convenient for pipeline installation.
3. Advanced valve seat: The valve seat, designed based on years of ball valve manufacturing experience, ensures a tight seal, has a low friction coefficient, and requires a small operating torque. There are various valve seat materials available, making it suitable for a wide range of applications.
4. Accurate handle: The flat-headed valve stem ensures that the connection with the handle will not be misaligned, thus guaranteeing that the handle indicates the correct open or closed position of the valve.
5. Locking device: To prevent misoperation when opening or closing the valve, there are locking holes at the fully open and fully closed positions to ensure the valve is in the correct position.
6. Anti-fly-off valve stem structure: The valve stem is installed from the bottom, preventing it from flying out under pressure. In case of a fire, it can form a metal contact with the valve body, ensuring the valve stem seal.
7. A ball valve uses a spherical body with a circular opening as the opening and closing component. Under the drive of the valve stem, the spherical body rotates around the center of the valve stem by 0 to 90 degrees to achieve the opening and closing function. It features a compact structure and quick operation. A 90-degree rotation can close the valve and cut off the medium in the pipeline. The diameter of the spherical body passage is the same as the pipeline diameter, resulting in low flow resistance and high flow capacity. The valve stem is installed from the bottom, eliminating the possibility of the valve stem flying out and ensuring safe use.

Frequently Asked Questions
What makes ball valves different in terms of flow resistance?
Among various valves, ball valves have the least flow resistance. When fully open, the medium can flow through almost without any loss due to the straight-line passage.
How do you operate a ball valve?
A ball valve can be fully opened or closed very quickly simply by rotating the handle 90 degrees.
What types of media are applicable for these ball valves?
They are highly versatile and suitable for water, gas, oil, natural gas, as well as acidic or alkaline corrosive media.
How does the valve stem design ensure safety?
It features an anti-fly-off structure where the stem is installed from the bottom. This prevents it from flying out under pressure and ensures a secure seal even in case of a fire.
Is there a way to prevent accidental misoperation of the valve?
Yes, the valve includes a locking device with locking holes at both the fully open and fully closed positions to ensure it remains securely in the correct state.
What is the advantage of the flat-headed valve stem?
The flat-headed valve stem ensures that the connection with the handle will not be misaligned, guaranteeing that the handle always indicates the true open or closed position.
