Flanged floating ball valve product features:
1, the advanced valve seat: the valve seat designed by many years' experience of ball valve manufacture ensures the valve seal, the friction coefficient is low, the operation torque is small, various seat materials and wide range of adaptation.
2, the switch is unmistakable handle: with the flat head stem, the connection with the handle will not be misplaced, thus ensuring the switch status indicated by the handle and the one of the valve.
3, locking device: to prevent misuse valve switch, the valve fully open, fully closed position with a lock hole, to ensure that the valve is in the correct position.
4, stem anti fly structure: the stem as download type to prevent pressure flying, while after the fire, the formation of metal in contact with the valve stem seal, ensure.
Suitable medium: water, gas, oil, natural gas and acid and alkali corrosive medium.
Suitable temperature: -196 ~ 350 C
Driving mode: manual, pneumatic, electric, hydraulic and so on.
Nominal path: DN 15-250 1/2 "~ 10"
