The bushing on the water conservancy valve is easy to contact with water due to the special working environment. Therefore, the bushing products used need to have very high reliability and self-lubricating maintenance-free performance, as well as special performance and requirements such as corrosion resistance.

Valve copper bushing

    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.
