Product Features

1. Floating ball valve with lip-shaped sealing seat, ensuring good sealing performance, low friction coefficient, and low operating torque.
2. Anti-blow-out stem structure: The stem is bottom-mounted to prevent it from being ejected under pressure. Additionally, it forms metal-to-metal contact with the body after a fire, ensuring stem sealing.
3. Fire-safe and anti-static device (for soft-seated floating ball valves).
4. Locking device: To prevent misoperation, locking holes are provided at the fully open and fully closed positions, ensuring the valve remains in the correct position.
5. Floating ball valves are suitable for frequent operation with rapid opening and closing; relatively small in size, lightweight, and easy to maintain; not limited by installation direction; low fluid resistance, no vibration, and low noise.
