**Meta Description:** Internal leakage in a **Ball Valve** leads to costly downtime. **Zhengzhou Runheng** experts analyze leakage causes from pipe flushing to **Metal-to-Metal Seat** selection. Inquire at: runhengmec@gmail.com.**Technical Content:** Ball valves are known for low flow resistance and quick operation, but internal leakage remains a challenge. **Zhengzhou Runheng** summarizes key preventative measures: * **Avoid Soft Seal Misuse:** In media containing sand or grit, PTFE seats are easily scarred. We suggest upgrading to a **Metal-to-Metal Seat** with supersonic spray-coated spheres. * **Stress Control:** Misaligned flanges can distort the valve body. **Zhengzhou Runheng** valves undergo rigorous torque testing to ensure mechanical stability under pressure. * **Routine Maintenance:** Even for self-lubricating valves, checking actuator stroke is vital to prevent erosion caused by partial closure.
