Export waterworks valves are typically accepted against API 6D, API 607 or ISO 9001, while the EU market additionally requires conformity with the scope of PED 2014/68/EU. These are the reference names buyers check during the approval stage; certificates are subject to the originals supplied by the customer.
Common market-entry requirements; applicability and documentation are subject to the destination country's current regulations and mutual confirmation.
Every soft-seated gate valve is traceable from casting batch to final shop test, and delivery dates and documents are met at the contract milestones.
Gate valves designed and manufactured to API 6D and API 607, sizes DN50–DN1200, ratings PN16/PN25/PN40 available.
Casting heat numbers, chemical composition and mechanical test reports follow the valve body and can be retrieved by batch.
Each valve undergoes shell strength and seat leakage testing, with test records issued and matched to the nameplate.
Body in A105 or F316 with seat rings, bonnet in forgings or castings, and duplex steel options — all selectable.
Standard sizes ship in 30–45 days; urgent bulk orders are scheduled with priority.
Packing lists, certificates of origin and a PED 2014/68/EU applicability statement are provided to support destination port clearance.
MOQ is 10 units per size (DN50–DN300); 5 units for DN350 and above. Mixed sizes are allowed within one order, with the MOQ calculated on a weighted unit-price basis; OEM private-label orders start at 100 units.
Stock sizes (DN50–DN300, PN16) ship in 15–20 days; non-standard and coated units take 30–45 days. We ship from Ningbo port; during the peak season (June–September each year) allow an extra 10 days.
Yes, we can supply 1 paid sample, credited against a bulk order. The sample ships with the material certificate, valve dimensional drawing and API 6D factory records; testing is carried out by a mutually approved third-party laboratory, which issues the report.
Each unit ships with the nameplate, material certificate (EN 10204 3.1), valve dimensional drawing and API 6D factory test records; bulk orders can include third-party inspection (SGS/Intertek). EU orders also come with the PED 2014/68/EU declaration of conformity and CE marking documentation.
Usual terms are 30% T/T in advance and 70% against a copy of the bill of lading; unsecured letters of credit are not accepted. Export packing is fumigated wooden crates with steel strapping, FOB Ningbo or CIF to major ports; we can also use your designated pallets.
Warranty is 12 months from commissioning or 18 months from ex-factory, whichever comes first. Wear parts such as the resilient seat ring, gate and stem are kept in stock by DN size and shipped within 5 working days of notification.
You receive selection advice and a lead time range within 24 hours, along with the specification sheets and inspection document list needed for your RFQ.
