Steel gate valves are commonly used in water supply and drainage projects, hydraulic and hydroelectric projects for water control and stoppage. They consist of components such as door frames, gate plates, sealing rings, and adjustable wedge pressure blocks. After prolonged use, the sealing surface of the steel gate can be adjusted with the wedge pressure blocks to ensure normal operation. Made of high-quality steel plates, these gates are coated with rubber for water stoppage and corrosion prevention, and are treated with sandblasting to remove rust and hot galvanized for added durability. Steel gate valves feature rational and sturdy structure, strong wear and corrosion resistance, reliable performance, and ease of installation, adjustment, operation, and maintenance. Durability: The lightweight steel structure is composed entirely of cold-formed thin-walled steel components, with the steel bones made from super corrosion-resistant high-strength cold-rolled galvanized sheets. This effectively prevents rust from affecting the steel plates during construction and use, thereby extending the service life of the lightweight steel components. The structural lifespan can reach 30 years.
