Fixed ball valve, is a new generation of high-performance ball valve, suitable for long distance pipeline and general industrial pipeline, its strength, security, and resistance to bad environment, special consideration when the design is suitable for all kinds of corrosive and non corrosive medium.The small make up to introduce the advantages of fixed ball valve.
1, sealing emergency greasing rescue: seat tightness due to medium foreign body or fire accident failure, greasing valve provides a connection to a quick note grease gun, convenient and quick to sealing grease injection to the valve seat sealing parts, reduce leakage.
2, reliable stem seal and low operating torque: in addition to setting the standard of sealing ring, the packing gland is also equipped with the "O" type sealing ring, double seal to ensure the reliability of the stem seal;Adding graphite packing and sealing grease injection makes the valve stem leakage after the fire to a minimum.Sliding bearing and thrust bearing makes the valve stem operation.
3, full size or reducing: can choose according to need full size or reducing structure.Full size valve flow aperture is consistent with the pipeline diameter, facilitate pipeline cleaning.
4, the valve stem can be lengthened: according to the needs of the installation or operation, can be extended to the valve stem.Extension rod ball valve, especially suitable for the occasion of city gas and so on need to be buried laying pipelines.Lengthen the stem size according to customers need to be addressed.
5, flexible operation, using a small friction coefficient and good self-lubrication bearing seat and stem, greatly reducing valve operating torque.So even in the case of the provided no sealing grease, is also a long-term mobility to operate the valve.
Above is about the advantage of ball valve is introduced, the hope can help to you.
