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

  Its testing facilities include spectral analyzers for material verification, ultrasonic and magnetic particle equipment for defect detection, and hydrostatic test benches for pressure validation. With pressure ratings from 150Lb to 2500Lb and temperatures from -196°C to 800°C, these forged steel gate, globe, check, and ball valves serve petrochemical and power industries through systematic quality assurance.
