The main disadvantages of ball valves are as follows:
- High opening and closing torque: Due to the structural characteristics of ball valves, their opening and closing torque is relatively large, requiring a large operating force to open or close the valve.
- Sealing performance is affected by temperature: At high temperatures, the sealing performance of ball valves may be affected, leading to leakage and other problems.
- Susceptible to wear: Friction between the ball and the seat of a ball valve can cause wear after prolonged use, requiring regular replacement.
- Unsuitable for throttling: Due to the structural characteristics of ball valves, they are not suitable for throttling adjustment, as doing so may cause damage to the valve.
- Higher price: Compared to other types of valves, ball valves are generally more expensive.
