Product Usage

The Z940H American standard electric gate valve is suitable for pipelines with ANSI Class150~2500, PN20~42, JIS10~20K, and operating temperatures of -29~425 ℃ (carbon steel) and -40~500 ℃ (stainless steel). It is used to cut off or connect the medium in the pipeline. By selecting different materials, it can be suitable for various media such as water, steam, oil, nitric acid, acetic acid, strong oxidizing media, and urea.

Product Features

① The product design and manufacturing meet the requirements of advanced foreign standards, with reliable sealing and excellent performance.

② The structural design is compact and reasonable, with a beautiful appearance.

③ Adopting a wedge type elastic gate structure and equipped with rolling bearings for medium and large diameters, it is easy to open and close.

④ The valve body material variety is complete, and the packing and gasket are reasonably selected according to actual working conditions or user requirements, which can be suitable for various pressure, temperature, and medium working conditions.

⑤ Adopting various domestic and foreign piping flange standards and flange sealing surface types to meet various engineering needs and user requirements.
