1. Emergency sealing grease injection rescue: The valve seat seal unexpectedly fails due to foreign matter in the Ball Valve medium or fire. The grease injection valve provides a quick connection with the grease injection gun. The imported pump injects sealing grease into the valve seat sealing part conveniently and quickly. , alleviate leakage.
2. Reliable
Valve Stem sealing and low operating torque: In addition to the standard sealing ring installed on the Ball Valve, the packing gland is also equipped with an O-ring. The double seal ensures the reliability of the valve stem sealing; additional graphite packing and sealing grease Injection minimizes valve stem leakage after a fire. Stem plain bearings and thrust bearings make the valve easy to operate.
3. Full bore or reduced bore: The Ball Valve can adopt full bore or reduced bore structure according to needs. The flow aperture of the full-diameter pipeline Ball Valve is consistent with the inner diameter of the pipeline, which facilitates pipeline cleaning.
4. The valve stem can be lengthened: The valve stem can be lengthened according to installation or operation needs. Extended stem Ball Valve is especially suitable for situations such as city gas that require buried pipelines. The size of the extended valve stem is determined according to customer needs.
5. Flexible operation: The use of valve seats and valve stem bearings with small friction coefficient and good self-lubricating properties greatly reduces the operating torque of the valve. This allows the valve to be operated flexibly and freely over the long term, even without sealing grease.
6. Make sure the pipeline and Ball Valve have been flushed before operation.
7. The operation of the valve is completed by driving the valve stem to rotate according to the input signal of the actuator: when rotating forward 1/4 turn (900), the valve is closed. When rotated 1/4 turn (900) in the opposite direction, the valve opens.
8. When the direction indicator arrow of the actuator is parallel to the pipeline, the valve is in the open state; when the indicator arrow is perpendicular to the pipeline, the valve is in the closed state.
