We’ve been running our own workshop in Zigong for more than 18 years, building deep, hands-on experience in OEM ball valve production for a wide range of industries.

As a professional ball valve manufacturer in China, we design and produce in full compliance with API 6D and ASME B16.34 standards. Our carbon steel, forged steel, and stainless steel ball valves all use certified materials, with complete MTR traceability available for every batch.
Custom Ball Valve Solutions: Floating & Trunnion Mounted

Whether you need floating ball valves for medium-pressure systems or trunnion mounted ball valves for high-pressure pipelines, we can deliver a solution that fits.
Quality You Can Verify for Yourself
Every valve is pressure tested according to API 6D requirements. We first obtained our official API 6D certification in 2016, and have maintained full, valid certification ever since — over 10 years of compliance with international standards.
