AWWA Resilient Seated Gate Valve

American standard cast iron gate valve (in compliance with API, ANSI and other standards) has become a core component of industrial pipeline systems with high reliability and wide applicability. Its advantages mainly include:

. High-strength material: A48/A126 standard ductile iron is used, which has corrosion resistance, wear resistance and compressive strength, and is suitable for water, steam, oil and weakly corrosive media;

. Strict sealing performance: The valve seat and gate adopt elastic seal (such as NBR, EPDM) or metal hard seal design, which is suitable for the temperature range of -20℃ to 300℃ and high-pressure working conditions (such as Class 150/300), effectively preventing internal leakage;

. Low flow resistance and efficient circulation: The full-diameter flow channel design reduces fluid resistance, ensures high flow efficiency and reduces energy consumption;

. Stable and durable structure: The valve stem is chrome-plated or nitrided for corrosion protection, and the stuffing box structure is optimized to ensure long-term opening and closing sealing and smooth operation;

. Standardization compatibility: in compliance with ASME B16.10/34 and other standards, the flange connection size is seamlessly compatible with the American standard system, which is convenient for global project installation and replacement;

. Flexible operation: supports manual wheel, gearbox or electric/pneumatic actuator drive to meet the automation needs of different working conditions;

. Convenient maintenance: modular valve cover and replaceable valve seat design reduce maintenance costs and extend service life;

. Economical and practical: cast iron material cost is low, the process is mature, and it has both mass production advantages and long-term use cost-effectiveness.

American standard cast iron gate valves are widely used in high temperature, high pressure or high frequency operation scenarios such as petrochemical, power, and municipal water supply due to their high sealing, strong adaptability and standardization advantages.
