1, floating ball valve lip seal seat, to ensure good sealing performance, small friction coefficient, small operating torque.
2, 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.
3, fire protection and anti-static device (soft sealed floating ball valve).
4, with locking device. In order to prevent the misoperation of valve switch, the valve fully open, fully closed position with a lock hole, to ensure that the valve is in the correct position.
5, floating ball valve for regular operation, quick opening and closing; relatively small size, light weight, easy maintenance, not limited by the direction of installation; fluid resistance is small, no vibration, noise is small.
[Valve structure drawing]
Applicable to water supply, petrochemical, metallurgy, mining, textile, energy, paper making, food, steel and other piping systems to switch the flow of medium, as well as the diversion of media or mixed fluid.
