Huaying has delivered a new batch of large-diameter gate valves,ball valves, and tilting disc check valves. Designed for large-bore service conditions, these products are built to meet stringent requirements for structural strength, sealing performance, and long-term operational reliability.

To ensure product quality, we have established a stringent control system across all stages of design, machining, assembly, and inspection. Key components are processed using high-precision CNC equipment, and assembly is carried out in a temperature-controlled clean environment. Critical procedures are executed by experienced technicians to ensure that operating torque, travel control, and sealing surface fit all meet design specifications. Dedicated inspection tools and in-line measurement methods are employed to guarantee assembly accuracy and interchangeability. Each valve undergoes shell strength and sealing tests in accordance with API 598 before delivery, with all test data fully documented and traceable. Process records and final inspections verify that all parameters conform, ensuring consistent performance and structural integrity across the entire batch.

From design to delivery, every detail is dedicated to achieving long-term, stable,and highly reliable operation—this is our standard, and also our commitment to every user.
