According to industry research from Growth Market Reports, both new‑valve manufacturing and valve refurbishment markets maintain steady global growth in 2026. More valve plant managers have realized that purchasing isolated single‑function equipment can hardly satisfy full‑process quality control. Qualified valve output calls for coordinated tooling covering sealing‑surface finishing, multi‑specification pressure testing and component press‑fitting, rather than only one test bench or one grinding machine.
In actual production scenarios, valve factories handle diverse product ranges, including gate valves, globe valves, ball valves, butterfly valves, check valves and safety relief valves. Each category brings distinct requirements for clamping mode, test medium and sealing‑surface machining. For butterfly and large‑diameter flanged valves, ordinary horizontal test benches cannot deliver proper clamping performance. Safety valves demand dedicated testing workflows for set‑pressure and reseating performance. Batch‑produced ball valves need special grinding devices for sphere and seat mating lapping. Besides, certain assembling steps such as lining pressing and component press‑in also require dedicated hydraulic press equipment.
Many factories used to source equipment from multiple different suppliers. This practice often creates problems: mismatched technical parameters, inconsistent after‑sales service, complicated spare‑parts procurement and difficult workflow integration. If grinding, pressing and testing devices come from separate manufacturers, technicians spend extra time adapting different operating logics, which lowers overall workshop throughput and increases the risk of non‑conforming products.
Yufeng Machinery has built a comprehensive product portfolio targeting the whole valve production and refurbishment workflow, instead of only focusing on several popular models.
For pressure‑testing links, our equipment family covers multiple series: horizontal top‑pressure test benches, jaw‑clamping test benches specially for large‑size flanged valves, D‑series dedicated butterfly valve test benches, vertical test benches for compact‑size workpieces, submerged‑type test benches for visual bubble‑leakage inspection, A‑series safety valve test benches, as well as PLC‑intelligent test benches supporting automatic pressure‑holding and digital report export. These units cover test range from DN15 up to DN1600‑2200, and can perform shell strength test, seat tightness test, back‑seat test and safety‑valve setting test, complying with API 598, GB/T13927 and ISO 5208 specifications.
For sealing‑surface reconditioning work, beyond planetary grinding machines and rotary worktables for flat‑part processing, we also supply QT‑series ball‑valve seat grinding machines, multi‑station grinding equipment and multi‑head valve‑seat grinders. Such devices handle sphere‑seat mating lapping for ball valves and mass reconditioning of valve seats and discs, helping factories get stable surface finish without heavy dependence on manual polishing.
We also provide special‑purpose valve hydraulic presses, which serve key assembling procedures including lining moulding, bushing press‑fitting and component correction. When matched with grinding and testing machines, it forms a closed‑loop workflow: component press‑assembly → sealing‑surface precision lapping → multi‑condition pressure inspection.
We understand different factories have differentiated conditions. Some customers are large‑scale OEM manufacturers with full‑volume mass‑production needs; others are medium‑and‑small workshops focusing on mixed‑batch orders and valve refurbishment. We do not push fixed combined packages blindly. Our technical team evaluates the customer’s actual product mix, main valve size range, required test standards and workshop layout, then recommends matched combination of standard‑model machines or develops non‑standard customized configurations.
Adopting coordinated full‑set equipment from one supplier brings tangible benefits: unified technical logic for operation and maintenance, simplified spare‑parts supply, consistent technical support and smoother connection between each production step. It helps valve factories reduce rework ratio, ensure test‑report validity and strengthen product competitiveness in global bidding and export business.
As valve‑industry quality standards keep getting stricter, complete‑chain supporting tooling will become one important competitive factor for valve producers worldwide. Yufeng Machinery will keep enriching our equipment lineup, providing one‑stop equipment selection, technical consultation and long‑term after‑sales service for valve manufacturers and refurbishment workshops across the globe. Feel free to share your product portfolio and process requirements, our engineers can work out targeted equipment proposals for you.
