The global valve market maintains stable growth, while industry analysts reach a consistent conclusion that the aftermarket repair segment delivers stronger resilience than new valve production. Many mature industrial markets in North America, Europe and the Middle East are not expanding large-scale new construction projects rapidly. Instead, plant operators choose to extend the service life of existing valves through professional inspection, pressure testing, seat lapping and recertification, rather than full replacement. This sustainable maintenance model has become a widely accepted cost-saving solution for end users.
API 598 (2023 11th edition) remains the widely accepted standard for valve shell test and seat leakage test for oil and gas valves. Any refurbished valve that will return to service must pass standardized pressure holding and leakage inspection before being put back into the pipeline system. This rule creates a continuous requirement for qualified valve test benches in repair workshops. Meanwhile, precision sealing surface reconditioning is the core procedure to recover valve sealing performance. Planetary grinding machines and rotary workbenches are widely adopted by valve repair companies for machining ball valve seats, sealing faces and mechanical seal parts, delivering stable surface finish and consistent lapping results.

Facing this clear industry trend, Yufeng Machinery actively adjusts its product layout and service system to fit the demands of valve aftermarket. We develop a complete equipment portfolio covering computerized valve test benches, vertical top-pressure test benches, planetary grinding machines and rotary worktables. Our equipment strictly follows API 598 and GB/T13927 standards, supporting automatic pressure holding, digital test report export and traceable test data, which greatly simplifies the certification work for repair companies.
Beyond standard equipment supply, Yufeng provides full-cycle supporting services. In the pre-sales stage, our technical team analyzes customers’ actual workshop conditions, valve types and testing requirements, and recommends suitable models or develops non-standard customized solutions for special-size valves and limited-space workshops. During production, we keep transparent communication and progress updates for overseas buyers. After delivery, we provide operation guidance, remote technical training, troubleshooting and spare parts support. We also keep optimizing equipment structure to reduce footprint while guaranteeing stable grinding and testing efficiency, solving the practical pain points raised by many repair workshop owners.
As the industry trend continues, valve repair workshops will continue to upgrade their hardware. Reliable, standard-compliant valve test benches and planetary grinding machines will remain essential tools for valve aftermarket service providers. Yufeng Machinery will continue to follow the development direction of the global valve aftermarket, iterate equipment performance and improve service capacity, helping valve repair partners around the world complete standardized valve testing and precision sealing surface lapping.
