Zhengyuan Valve Group Co., Ltd. has established a comprehensive process system covering precision die forging, CNC machining, heat treatment, and full-scale testing. Using advanced die forging technology, the company produces valve bodies with a dense metal structure that effectively eliminates casting defects such as porosity and inclusions, thereby enhancing strength and pressure-bearing capacity.

  The sealing faces are overlaid with Stellite hard alloy and then mirror-finished through a multi-step lapping process. This ensures excellent sealing performance under high-temperature, high-pressure, and corrosive media. Following GB/T 13927 standards, each valve undergoes 100% shell strength testing at 1.5 times the rated pressure and seat leakage testing. 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 are widely used in petrochemical, power, and other critical industries.
