Rubber Check Valves with slow corrosion, anti-aging, deformation, strong adaptability, long life, use of a wide range of characteristics such as check valve is suitable for the chemicalSwing check valve class 900Lb industry the ideal check valve check valve sewage treatment equipment . The check valve is an all rubber product structure, appearance was 'duckbill-like', with 'positive drainage, reverse-return' feature of the new water supply and drainage valves, solve valve check valve used in the past operation in poor condition, leaking Swing check valve class 1500Lblarge, easily corroded hinge pin, slag deposition, valve seat wear, need regular maintenance and replacement and other technical problems. The check valve may be different conditions, using different design mechanisms, use different rubber formulations, according to special Swing check valve class 600Lbtechnology produced. The check valve used in a variety of chemical sewage treatment works discharge effluent to prevent backflow, back, to avoid secondary pollution, and the valve body does not produce biofilm surface can be antiseptic sterilization, is to replace the traditional non-return ideal valve.
