Steel gate valves are commonly used in water supply and drainage projects, hydraulic and hydroelectric engineering as water拦堵 and stopping equipment, consisting of door frames, gate plates, sealing rings, and adjustable wedged pressure blocks. After prolonged use, the sealing surface of steel gate valves can be adjusted with wedged pressure blocks to ensure normal operation. Made from high-quality steel plates, these gate valves are coated with rubber for water stopping and corrosion resistance, and are treated with sandblasting and hot galvanizing for surface preparation. They feature reasonable and sturdy structure, strong wear and corrosion resistance, reliable performance, and ease of installation, adjustment, use, and maintenance. Durability: The lightweight steel structure is composed entirely of cold-formed thin-walled steel components, made from super corrosion-resistant high-strength cold-rolled galvanized steel plates, effectively avoiding the impact of rust on steel plates during construction and use, thereby extending the service life of lightweight steel components. The structural lifespan can reach 30 years.
