About Yonggao Co., Ltd. - Industrial Valves & Gauges Supplier in China

China, with a catalogue of 8 listed products, Yonggao Co., Ltd. supplies items in the industrial valves & gauges, plumbing fittings, and industrial couplings segments. The catalogue includes PVC swing check valve, PVC valves, union ball valve, check valve II, AS1477 PVC fittings, plastic union, compression coupling, and compression coupling III. These products are classified under HS chapter 84 for valves (e.g., HS 8481) and HS chapter 73 for metal couplings and fittings (e.g., HS 7307‑7308). The supplier’s listings do not specify additional certifications, so buyers typically verify compliance with ISO 9001 or CE marking for similar goods.

Product Range and Specialties of Yonggao Co., Ltd.

The listed items cover PVC swing check valve, PVC valves, union ball valve and check valve II for the valve segment, AS1477 PVC fittings and plastic union for the plumbing segment, and compression coupling and compression coupling III for the industrial coupling segment. PVC components are normally produced from unplasticized PVC (PVC‑U) to ISO 9001 standards, with pressure classes ranging from PN 4 to PN 16 and dimensions defined by DN 15‑200. Metal couplings are typically forged from carbon steel or stainless steel, conform to ISO 9001 and are marked to the relevant EN 1092‑1 pressure‑class tables. Typical industry grades include PVC‑U schedule 40 for valves and fittings, and class 150 or class 300 for steel couplings, all supplied in bulk bags or 20‑ft containers.

Trade and Export Information - Yonggao Co., Ltd.

Exporters of industrial valves, plumbing fittings and couplings from China commonly ship to Southeast Asian, Middle Eastern, African and European markets, where water‑distribution, oil‑and‑gas and construction projects drive demand. HS 8481 covers the valve products, while HS 7307 and HS 7308 cover the metal couplings and plastic fittings; customs authorities often request material safety data sheets and test certificates for these codes. Buyers usually require CE marking, ISO 9001 quality‑management certification, and where applicable UL or ASTM test reports. Standard logistics involve 20‑ft or 40‑ft containers, with Incoterms such as FOB Shanghai or CIF destination port; packaging is typically in sealed polyethylene bags (25 kg each) or wooden crates for larger couplings.

Sourcing from Yonggao Co., Ltd. - Buyer Guidance

When sourcing PVC swing check valves or other PVC components, request the material certification (e.g., GB /T 5009), pressure‑rating test report and dimensional drawing to confirm DN size and PN class. For compression couplings, ask for mill‑test reports, corrosion‑resistance data and the applicable ISO 9001 or EN 1092‑1 compliance documents. Verify that packaging specifications meet the shipment mode - bulk bags for small parts, wooden pallets or crates for larger metal couplings - and confirm the HS code declared on the commercial invoice matches the product type. Request a sample batch before full order to assess the PVC hardness (Shore A 85‑90) or metal tensile strength (≈400 MPa for carbon steel couplings).

What pressure classes are available for the PVC swing check valve?

Typical PVC swing check valves are offered in PN 4, PN 6 and PN 10, with a maximum operating pressure of about 1.6 MPa at 20 °C.

Which size standards apply to the compression couplings?

Compression couplings are normally sized according to DN 15‑200 (½‑inch to 8‑inch nominal diameter) and conform to EN 1092‑1 class 150 or class 300 pressure ratings.

What material certification should be requested for the PVC fittings?

Buyers should ask for a GB /T 5009 or ISO 9001 certificate confirming the product is made from PVC‑U and meets the specified hardness and impact‑strength values.

Are test reports required for the union ball valve?

Yes, a pressure‑test report (hydrostatic test at 1.5 × rated pressure) and a dimensional inspection report are standard for union ball valves.

What packaging is typical for the plastic union items?

Plastic unions are usually packed in sealed polyethylene bags of 25 kg each, with the total quantity placed on standard 1200 mm wooden pallets for container loading.

Which HS codes are used for the valve and coupling products?

Valve products fall under HS 8481, while metal compression couplings and plastic fittings are classified under HS 7307‑7308, which customs authorities reference for duty assessment.

What documentation is common for export compliance from China?

Exporters generally provide a commercial invoice, packing list, certificate of origin, material safety data sheet and any requested quality‑management certificates such as ISO 9001.

What lead time is typical for a first order of these items?

First‑time orders of PVC valves or couplings from Chinese manufacturers usually require 4‑6 weeks for production and container loading, depending on order size and required certifications.
