Zhengyuan Valve Group Co., Ltd. has enhanced the pressure resistance of its forged steel gate, globe, check, and ball valves through advanced die‑forging and full‑process pressure testing. The die‑forged valve bodies have a dense, defect‑free structure, delivering higher tensile and yield strength for reliable performance under high pressure.

  Each valve is tested according to GB/T 13927. Shell strength tests are conducted at 1.5 times the rated working pressure, and seat sealing tests verify zero leakage of static seals. With pressure ratings from 150Lb to 2500Lb, these valves are approved by major oil and chemical companies and are widely used in thermal power plants, hydrotreating units, and other high‑pressure systems.
