Principle of the forged steel floating ball valve: This kind of ball valve has a floating ball supported by two valve seats. Under the medium pressure effect, a certain displacement can be generated by the ball itself so as to be pressed onto the seat seal ring at the outlet, guaranteeing tightness at the outlet.
- The ball valve are designed in accordance with ISO17292, API 608, BS 5351,GB/T 12237.
- Simple structure with good tightness and small torque.
- Have reduce bore type and full bore type with the minimum flow resistance (zero actually).
- Low emission packing.
- Fire safe, anti-static and anti-blowout stem design.
- Optional locking device.
- Optional ISO 5211 top flange.
