Self-sealing forged steel gate valve (pressure self-tightening bonnet) bonnet design, the first is a bolt-type bonnet, which is connected by concave and convex surfaces, using stainless steel belts and flexible graphite spiral wound gaskets, and ring connections can also be used as required. The second type is a welded bonnet, which is sealed by threads and then welded. Rigid welding can also be used directly as required. The third is a self-sealing bonnet, which is connected to the self-sealing bonnet through threads.
Self-sealing forged steel gate valve class 900Lb~2500lb, working temperature -29~425℃ (carbon steel) or -29~500℃ (stainless steel) on small-diameter pipelines, used to cut off or connect the medium in the pipeline, different selection The material can be applied to various media such as water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea, etc.
