Lightweight: Made of ductile iron, the body is about 20%~30% lighter than traditional gate valves, making installation and maintenance easy. Flat-bottomed gate seat: Traditional gate valves often accumulate foreign objects like stones, wood blocks, cement, iron shavings, and debris in the valve seat groove after water flushing, which can lead to loose closure and leakage. The elastic seat gate valve bottom features a flat design identical to pipe machines, preventing debris accumulation and ensuring smooth fluid flow. Full-gum coated: The gate plate is coated with rubber on both the inner and outer surfaces. Precision casting body: The valve body is precision cast, with geometric dimensions that ensure the valve's sealing without any additional finishing.
