Quality & Material Authenticity

How do I verify the material is genuinely 316L / CF8M — not substituted?

Every heat of raw material arrives with an EN 10204 3.1 Material Test Certificate (MTC) issued by the mill.

We run a four-gate QC system: IQC (incoming material) → IPQC (in-process machining) → FQC (assembly dimensional & visual) → OQC (final pressure & leakage test).

Customization & OEM/ODM

What customization and OEM/ODM services do you offer?

We support full OEM and ODM development. Customizable parameters include: body material (WCB, CF8/CF8M ,CF3M), trim material, end connections (ANSI/DIN/JIS flange, NPT/BSP thread, butt-weld), pressure class, bore size, seat type (PTFE/RPTFE soft-seal or metal-to-metal), actuator mounting (electric, pneumatic, hydraulic), and coating/painting. For branding: custom logo , private-label nameplate, and OEM packaging.

Yes. We supply complete actuated valve assemblies — electric (on/off or modulating), pneumatic (single- or double-acting), or gear-operated handwheel — fully assembled, wired, and function-tested before shipment

Lead Time & Delivery

What are your standard lead times, and can you expedite urgent project orders?

In-stock items ship within 5-7 business days; standard production orders 20-30 days; OEM/custom orders 40 days. For urgent requirements we offer priority production scheduling — please flag urgency at the RFQ stage. We maintain buffer stock of fast-moving SKUs (common DN/NPS sizes in CF8M and WCB) to support spot orders. Our 24-hour response commitment means delivery confirmation within one working day of order placement.

We accept: EXW (Wenzhou factory), FOB Ningbo/Shanghai, CIF. Shipping modes: sea freight (FCL/LCL), air freight, express courier (DHL/FedEx/UPS), and China-Europe rail for EU buyers. Our European office in Budapest, Hungary enables local logistics coordination for EU customers.
