Advantages of floating ball valve

  1. Low torque: Floating ball valves have a lower torque requirement than trunnion mounted ball valves, making them easier to operate.
  2. Tight seal: The floating ball design allows for a tight seal between the ball and the seats, reducing the risk of leakage.
  3. Versatile: Floating ball valves can be used in a wide range of applications, including high-pressure, high-temperature, and corrosive environments.
  4. Easy maintenance: The simple design of floating ball valves makes them easy to maintain and repair, reducing downtime and maintenance costs.
  5. Cost-effective: Compared to other types of valves, floating ball valves are often more cost-effective, making them a popular choice for many applications.
