Valve copper sleeve bushing

    Bushings on large valves Due to the special working environment, the bushing products used require very high reliability, self-lubricating and maintenance-free performance, as well as special performance and requirements such as corrosion resistance. According to the customer's different use environment and requirements, our company chooses the embedded self-lubricating bearing produced by different materials, which can significantly improve the reliability and service life of the bushing products; the embedded self-lubricating bearing mainly chooses high-performance aluminum such as ZCuAl9Fe4Ni4Mn2 and ZCuPb10Sn10. Bronze or tin bronze material is a base material with a solid lubricant embedded on the surface. It has excellent self-lubricating properties. Under low speed and heavy load, the performance and life are much higher than ordinary tin bronze or aluminum bronze products, and it has maintenance-free performance. And higher reliability of use. Widely used in fresh water, seawater, petrochemical, steam and other corrosive and polluting environments.
