The wedge valve with a retractable spindle made of stainless steel 30nzh64nzh is used on pipelines transporting various media: cold/hot water, steam, gas, non-aggressive petroleum products and oil. That is, any environment that is non-aggressive to the material of the valve body. If there are coarse impurities (particles) in the transported medium, it is recommended to install a filter before the valve. The main feature of 30s64nzh is a retractable spindle, which serves to significantly reduce hydraulic resistance.
