Ordering
Stock versus made to order
Regular items ship from stock. Everything else — a thread we do not hold, a grade outside the line, a build to your print — is made to order and quoted per job. Each tile above says which grade and thread we keep ready for that series.
Samples are available and charged for. Minimum order depends on the model and the marking, so we settle it in the quote rather than posting a number that fits nothing.
Quality
What travels with the shipment
Mill test report for the body material. ISO 9001 quality system. CE marking.
Nothing else is claimed here. If a certificate is not on this list, we do not hold it.
OEM & private label
Valves under your own name
For valve brands with no plant of their own, equipment and skid builders, and distributors running a private line. You hold the customer and the specification; we run the production.
Laser marking, stamping, labels and printed cartons to your artwork. Built to your drawing, not only to our catalogue.
The company
We cast our own bodies
We run our own foundry and our own assembly floor in Wuqi, Taichung — the casting is ours, not a subcontractor's. Stainless only, CF8 and CF8M, since 1999. We make no carbon steel bodies, so nothing gets substituted mid-order.
Send a part number, a spec sheet or a photo. We will price it.
