FAQ for Stainless Steel Ball Valves and Custom Valve Assemblies

What is your MOQ for stainless steel ball valves?

Our standard MOQ is 10 valves per size and configuration. For custom valve assemblies, we confirm quantities after reviewing the P&ID, connection standard, material grade and actuator requirements.

Can we order samples before a production run?

Yes. One sample can be supplied for dimensional, material and functional review. We issue a drawing and quotation first, then confirm sample lead time and freight before production approval.

What are the lead times for valves and assemblies?

Standard valves normally ship within 4–6 weeks after drawing approval and deposit; samples require about 1–2 weeks. Custom assemblies receive a separate schedule covering procurement, machining, assembly and testing.

How do you perform pressure testing and inspection?

Each valve is pressure-tested to EN 12266-1 requirements, with shell and seat-test results recorded. We can provide dimensional inspection, material verification and an inspection report with the shipment.

Which documents are supplied with the order?

The shipping file can include the commercial invoice, packing list, test report, certificate of conformity and EN 10204 3.1 material certificates. ISO certification details are confirmed for the applicable production site.

What payment, packaging and warranty terms apply?

Our standard terms are 30% deposit and 70% before shipment. Valves are individually protected and packed in export cartons or cases; warranty claims are reviewed against inspection records and agreed contract terms.
