The main corrosion resistance characteristics of Hastelloy needle valve: excellent resistance to reducing acid medium. Especially in high-temperature hydrogen fluoride gas and hydrofluoric acid solution, it has excellent corrosion resistance, and can resist the corrosion of hydrofluoric acid solution of any concentration. It is mainly used in high temperature hydrogen fluoride gas and hydrofluoric acid solution.

Hastelloy needle valve is an important part of instrument measurement pipeline system. It mainly has cut-off shape and spherical shape, and its function is to open or cut off the pipeline passage. Hastelloy needle valve has the advantages of convenient installation and disassembly, tight connection, fire prevention, explosion-proof, high pressure resistance and good sealing performance. It is an advanced connection valve in power stations, oil refining and chemical plants and instrument measurement pipelines. Hastelloy needle valve has good sealing performance and long service life. Even if the sealing surface is damaged, it only needs to replace vulnerable parts to continue to use. During installation, the flow direction of the medium should be consistent with the direction of the arrow on the valve body.
