Our standard price for a 6-inch 150LB 316L flanged ball valve (full bore, standard trim) ranges from $210 to $280, depending on volume and specific trim requirements (e.g., hard coating, stellite seats). Contact us for a firm quote based on your specs.

Yes. We offer tiered pricing based on order quantity. Typically, orders over 50 units receive a 5-8% discount, and orders over 200 units receive up to 15% off the base price. We are happy to provide a volume discount schedule.

For OEM designs requiring new patterns or custom machining, lead times are typically 10-12 weeks. Standard design modifications (e.g., stem length, bypass) are usually 6-8 weeks. We provide a detailed project timeline upon order confirmation.

We adhere to a strict 3-stage QC process: 1) Incoming raw material inspection (PMI & certificates), 2) In-process inspection during machining and assembly, 3) Final inspection including hydrostatic testing, shell testing, and visual examination. All records are traceable by heat number.

Our standard MOQ is 10 pcs for popular sizes (1/2" to 8"). For larger sizes (10" and above) or specialized valves, the MOQ is 5 pcs. We understand the need for flexibility and can discuss lower MOQs for sample orders or project kick-offs.

Absolutely. We provide EN 10204 3.1 material certificates and PMI test reports as standard with every shipment. Third-party inspection (e.g., SGS, BV) is also welcome and can be arranged at the factory.

Our prices are generally 20-40% lower than equivalent European or American manufacturers while maintaining comparable material standards (ASTM, ASME). The savings come from our integrated supply chain and lower manufacturing overheads, not from cutting corners on quality or testing.
