Definition: A gate valve designed in accordance with international standards such as API, ANSI, DIN, using bellows as the stem sealing element, suitable for industrial pipeline systems with high sealing requirements, and capable of fully opening/closing medium flow.

Core features:

Bellows sealing: Stainless steel or Inconel bellows replace traditional packing to achieve zero leakage of valve stem, especially suitable for toxic and flammable media;

Double protection design: Some models combine corrugated pipes and packing boxes to form a double seal, improving safety and durability;

Full bore flow channel: The valve disc moves in a straight line along the centerline of the fluid, reducing flow resistance and suitable for high-purity or easily vaporized media;

International standard adaptation: The valve body material (carbon steel, stainless steel, etc.) and process comply with regulations from multiple countries, and are suitable for complex working conditions such as high pressure and high temperature.

Typical applications: Pipelines that require strict leak prevention in the petrochemical, pharmaceutical, power system, and nuclear industries, such as the transportation of liquefied natural gas and corrosive chemicals.

Advantages: superior sealing performance compared to traditional gate valves, low maintenance costs, support for manual/gear drive, meeting international environmental and safety standards.
