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.

Forged steel valves are mainly used in the pipelines of various systems in thermal power plants to cut off or connect pipeline media. Applicable medium: non-corrosive medium such as water and steam. Compared with other valve products, forged steel valves are characterized by high temperature and high pressure, unique self-sealing design, the higher the pressure, the more reliable the sealing. Due to the special performance, technical characteristics and working conditions, the product has also become a substitute for other products.

The products adopt ISO, API, ANSI, BS, DIN, NF, JIS, JPI, GB, JB and other advanced domestic and foreign standards. The product diameter is 3/8"-2" (DN10mm-50mm), and the pressure rating is 150Lb- 2500Lb (0.1Mpa-42.0Mpa), working temperature is -196℃-680℃.
