Structure and Characteristics of Welded Ball Valve

Welded ball valve structure: 1. Welded ball valve with carbon steel seamless pipe pressure forming integral welding ball valve. 2. Stem using AISI303 stainless steel, stainless steel body with AISI304, refined by grinding production, with excellent sealing performance and corrosion resistance. 3. Sealed carbon reinforced PTFE bevel elastic seal negative pressure on the spherical surface, so that the seal reaches zero leakage, long life and other advantages. 4. The valve connection: a welding, thread, flange, etc. for the user to choose. Transmission: The handle, turbine, pneumatic, electric and other transmission structure, flexible switch light. 5. Welded ball valve The valve structure is compact, light weight, easy to heat, easy to install. This valve is normally installed horizontally. 6. One-piece welded ball valve to learn advanced foreign technology, combined with the actual situation of the domestic research to domestic instead of imports, to fill the gaps. Widely used in natural gas, petroleum, heating, chemical and thermal pipelines and other long-distance pipeline. Features: 1. The valve body is welded by a steel pipe. 2. Ball pad with reinforced PTFE. 3. Stem explosion-proof design. 4. Temperature range: -60-200 ℃ 5. Drive: manual or turbine drive. 6. Testing standards: Api 598

Aluminum Alloy is a kind of nonferrous metal structural materials widely used in industry, has been widely used in aviation, aerospace, automotive, machinery manufacturing, shipbuilding and chemical industry.
