A Brief Introduction to American Standard Cast Steel Gate Valves

Flange-connected steel gate valves are suitable for use with ANSI Class 150 to 900 and PN 2.0 to 16.0 MPa ratings, and are designed for use in cutting off or connecting media in pipelines operating within temperatures ranging from -29 to 425 ℃ (carbon steel) and from -40 to 500 ℃ (stainless steel).

Detailed Information on American Standard Cast Steel Gate Valves （1） Purpose: Flange-connected steel gate valves are suitable for use with ANSI Class 150 to 900 and PN 2.0 to 16.0 MPa ratings, and are designed for use in cutting off or connecting media in pipelines operating within temperatures ranging from -29 to 425 ℃ (carbon steel) and from -40 to 500 ℃ (stainless steel). By selecting different materials, these valves can accommodate various media such as water, steam, oil, nitric acid, acetic acid, strong oxidizing media, and urea. They are available in manual, bevel gear-driven, and electric models. （2） Structural Features: ① The product design and manufacturing comply with advanced foreign standards, ensuring reliable sealing and excellent performance. ② The structural design is compact and reasonable, with an aesthetically pleasing appearance. ③ A wedge-shaped elastic gate structure is employed, with rolling bearings installed for medium to large diameters, facilitating easy opening and closing. ④ The valve body offers a wide range of materials, and the packing and gasket are carefully selected based on actual working conditions or user requirements, making them suitable for various pressure, temperature, and medium conditions. ⑤ The valves adopt various domestic and international piping flange standards and flange sealing surface types, meeting diverse engineering needs and user requirements.
