Product Features
- Floating ball valve with lip-shaped sealing seat, ensuring good sealing performance, low friction coefficient, and low operating torque.
- 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.
- Fire-safe and anti-static device (for soft-seated floating ball valves).
- 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.
- 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.
