Rust Prevention

The inner layer of the valve's outer surface is coated with a water-based anti-rust primer, and the outer layer is coated with a two-component water-based topcoat, preventing corrosion and rust.

High Temperature Resistance

The casting is made of WCB material, the sealing element is made of graphite + stainless steel, and the sealing area is made of hard stainless steel, capable of withstanding temperatures up to 425℃.

Optimized Design 

The stem is made of 12Cr13, and the stem nut uses lubricated brass. A bearing is installed between the nut and the bracket, giving the valve excellent wear resistance and reducing torque.

Rigorous Testing

Our chemical gate valves meet API 598 testing requirements.

Leakage Prevention

The sealing surface is overlaid with hard stainless steel, with high machining precision and a sealing surface roughness of Ra0.4, ensuring zero leakage.

Strict Standards

Wall thickness, structural design, stem diameter, and sealing performance all meet API standards.
