In the metal and minerals industry, the combination of the erosive slurry, corrosive chemicals, and elevated temperatures and pressures present a difficult application for any valve. For example, the refining of bauxite into alumina (aluminum oxide) requires the use of lime and caustic soda. The bauxite is ground and mixed with chemicals then heated (400°F - 450°F) in digesters at pressures up to 500 psi.
The Series V701 has been successfully applied for decades in the metals and minerals industry. Designed to handle difficult services involving erosive fluids and slurries, its expanded body and Venturi seat ring construction minimizes erosion in even the toughest applications.
