In shipbuilding and marine engineering, ballast water systems operate in high‑chloride seawater environments, where corrosion resistance is critical. Zhengyuan Valve Group Co., Ltd. supplies forged steel gate, globe, check, and ball valves made from stainless steel and alloy steel to meet these demands.

  Stainless steel valves form a dense chromium‑rich oxide film that resists chloride attack, while 316L stainless steel with added molybdenum offers enhanced seawater corrosion resistance. Forged steel valves feature a compact metal structure, providing longer service life than cast valves. They cover pressure ratings from 150Lb to 2500Lb, temperatures from -196°C to 800°C, and comply with API 6D and GB/T standards. Intelligent valves enable remote status monitoring, supporting predictive maintenance. With end‑to‑end quality control and a Special Equipment Manufacturing License, Zhengyuan provides reliable flow control solutions for ballast water systems and marine pipelines.
