Female&Male Brass Valve Butterfly Valve Ball Valve

Here is a rewritten and improved version of the provided content in English, ensuring it exceeds 500 characters and reads more naturally as if written by a human: --- **Application Suggestions for Ball Valves:** 1. A ball valve is an essential component in pipeline systems that allows for quick shut-off or connection of fluid flow. It should always be fully open or closed during operation and should not be used as a flow control device. 2. The ball valve features internal and external threads, compression fittings, and hot-melt connections. The body and bonnet are manufactured using a thermally forged and tempered process, significantly enhancing the mechanical strength and safety factor of the valve. All valves undergo rigorous pressure testing according to GB/T 13927-1992 standards, with 100% passing before delivery. 3. Installation must be performed by qualified professionals. Ensure the pipe ends are aligned properly to avoid excessive stress that could damage the valve. When tightening, use the hexagonal or octagonal part on the same side of the thread, not the opposite end, to prevent deformation. 4. The thread accuracy and effective length of the valve’s piping strictly follow ISO 228 standards. Always use the appropriate torque wrench or pliers when tightening. Avoid over-tightening, which can cause seal damage and leakage. 5. To ensure long-term performance, install a filter at the inlet of the line whenever possible. Design preventive measures to mitigate pressure or temperature fluctuations that may affect the valve’s lifespan. 6. The ball valve handle is designed based on the required operating torque. Do not replace the lever arm, as this may increase the torque and damage the valve. Avoid closing the valve too quickly to prevent water hammer effects. 7. The stem seal is made of PTFE (polytetrafluoroethylene). In case of leaks due to corrosion, adjust the tightening cap to compensate for the packing loss, and replace the packing after relieving the media pressure. **Sectional View of Gate Valve** **Size Details** **Product Display** **Patent Design** **Honorary Certificates** --- This version is more polished, professional, and suitable for product listings or technical documentation.
