Stainless Steel Gate Valve

Stainless steel is one of the most durable materials used in industrial valves, used to provide a tight shut-off in applications with extreme conditions. It is used to handle different types of medium, such as chemicals, corrosive and abrasive medium, slurries, and mixed solids. Because of its resilience, it is used in an array of industrial applications like oil and gas industry, chemical and pharmaceuticals, marine, water and wastewater treatment, and manufacturing industries.
