In industrial systems, the stable operation of valves always depends on the precision of their accessories. The valve body, valve stem, valve seat or valve cover may seem ordinary, but every tolerance and every surface treatment will directly affect the seal...

We have updated our execution rules for drawing review and first-article inspection to shorten turnaround and control the features that affect sealing and assembly. The review now checks: material confirmation (e.g., CF8M, A105, 316L, 17-4PH), heat treatment...

To meet orders scheduled for Oct–Dec 2025, we have adjusted machining shifts and coordinated upstream casting/forging slots. Priority is on components where geometry drives sealing performance: CF8M cast valve bodies, A105 forged valve bodies, 316L/PEE...

Chengdu, China | September 15, 2025 Sichuan Yining Machinery introduced a project-ready mounting pack that bundles torque-path parts and interfaces for faster assembly and commissioning on chemical, energy, and water projects. The pack offers 17-4PH va...

We are standardizing traceability and export packaging for every valve part we ship. The new valve marking system links each valve to its heat number and batch, while the consolidated documents and labels speed valve receiving and audits. Traceability ...

We’ve tightened in-process and final QC for valve body, bonnet/cover, ISO 5211 bracket, coupling, and trunnion lower stem to cut rework and speed fit-up. What’s new F2F: production target ±0.15 mm (meets drawing); light skim cut af...

Why this matters: Turnarounds and new builds are overlapping, tightening capacity at foundries/forges, large-bore machining, and third-party labs. A clean technical freeze before PO remains the fastest lever for on-time delivery. Market snapshot ...

In the last year, procurement teams across oil & gas, chemical, and power plants have tightened specifications for the valve body at the heart of isolation and control assemblies. A high-integrity valve body is no longer judged only by alloy and weight; buye...
