Industrial Cluster

Rooted in the Yongjia-Longwan corridor

Operating directly within China's primary valve manufacturing hub, we eliminate trading-house layers to consolidate multi-material piping schedules into containerized export shipments.

Our integrated supply chain bridges foreign engineering contractors and valve distributors directly to primary machining and testing facilities.

Export crating and MTC

Positive material identification spectrometer testing verifies chemical composition of cast iron, WCB, and CF8M stainless steel.

High-tolerance multi-axis milling ensures exact flange face finish and stem alignment against ASME and DIN standards.

Final inspection, corrosion protection coating, and generation of EN 10204 3.1 material test certificates prior to crating.

Every valve undergoes shell and seat leakage testing per API 598 or EN 12266 using calibrated test benches.

Traceable metallurgy and documentation

All export orders ship with comprehensive EN 10204 3.1 inspection documentation and complete heat number traceability.
