What we check, and what we can prove

Valves are pressure and leak tested before shipment.

Dimensions are checked against the drawing before packing.

A mill test report for the body material ships with every order. If your customer audits the chain, the certificate is already in the box.

ISO 9001 quality system. CE marking.

That is the complete list. If a certificate is not named here, we do not hold it — we will not claim food-grade, API, FDA or 3-A approval we cannot produce on paper.

We run our own foundry and our own assembly floor in Wuqi, Taichung. The castings are not bought in from a subcontractor.

We make stainless bodies only — CF8 and CF8M. There is no carbon steel on the floor, so there is nothing to substitute or cross-contaminate mid-order.
