Wi-clamp connection check valve

Corrosion-resistant valve is a valve specially used for corrosion-resistant media, mainly made of corrosion-resistant materials, such as stainless steel, titanium alloy, Hastelloy, etc. Corrosion-resistant valves have the characteristics of strong corrosion resistance, long service life and reliable performance. They are widely used in petrochemical, electric power, metallurgy, water treatment and other fields, especially for the transportation and control of corrosive media.
