As one of the important industrial equipment, cast steel gate valves have excellent performance, but they may face the possibility of rusting due to various factors such as material, environment, and usage conditions.
There are several methods here to make cast steel gate valves less prone to rusting and effectively prevent rusting.
Method 1 (Enhance Corrosion Resistance): Use materials with good corrosion resistance, such as stainless steel and alloy steel.
Method 2 (Improving Surface Finish): Sandblasting treatment, spray coating treatment, electroplating treatment.
Method 3 (Reduce Wear and Corrosion): Regularly clean, lubricate, and tighten.
