Forged steel gate valves are suitable for small-diameter pipelines with Class 150~2500 and working temperatures of -29~425 ℃ (carbon steel) or -29~500 ℃ (stainless steel). They are used to cut off or connect media in pipelines. Different materials are selected and can be applied to various media such as water, steam, oil, nitric acid, acetic acid, oxidizing media, urea, etc
