Water pipes on the valve due to the special nature of the work environment, easy access to water. So the use of the sleeve products need to have a very high reliability and self-lubricating maintenance-free performance, as well as anti-corrosion pollution and other special performance and requirements.

                                            Valve copper sleeve

    According to the different use of the customer environment and requirements, our company chooses different materials to produce mosaic self-lubricating bearings, can significantly improve the reliability and service life of the sleeve products; mosaic self-lubricating bearings mainly choose ZCuAl9Fe4Ni4Mn2 and ZCuPb10Sn10 and other high-performance aluminum Bronze or tin bronze material as the matrix, the surface of solid lubricants, with excellent self-lubricating properties, in the low-speed and heavy load occasions, the use of performance and life is much higher than ordinary tin bronze or aluminum bronze products, and maintenance-free performance And higher use reliability. Widely used in fresh water, sea water, petrochemical, steam and other corrosion and pollution of the environment.
