Zhengyuan Valve Group Co., Ltd. has established a comprehensive testing system to ensure product reliability. Each valve undergoes shell strength testing at 1.5 times the rated working pressure and seat leakage testing according to GB/T 13927 standards, with test pressure set at 1.1 times the rated working pressure.

  Equipped with spectral analyzers for material verification, ultrasonic and magnetic particle testing for defect detection, and hydrostatic test benches for pressure validation, the company ensures valves meet applicable requirements for shell integrity and sealing performance.

  With pressure ratings from 150Lb to 2500Lb and temperature ranges from -196°C to 800°C, these forged steel gate, globe, check, and ball valves serve petrochemical, power, and other critical industries, supported by API 6D and GB/T certifications.
