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℃.
