The Flanged Stainess Steel Swing Check Valve supplied by Dongying Lake Petroleum Technology Co., Ltd. is a back‑flow prevention device for pipeline systems. The valve body is fabricated from ASTM A351 CF8 stainless steel, and the internal components follow the material grades listed in the source. The product is designed according to API 6D, BS 1868 and API 594 wafer‑type standards, with flange connections complying with ANSI/ASME B16.5 for NPS 24 and larger sizes using ASME B16.47A.
Stainless‑steel construction offers corrosion resistance suitable for oil‑field and chemical‑process environments. The valve incorporates a swing disc that opens under flow, a common configuration that provides low pressure drop and reliable sealing. The listed inspection regime includes API 6D and API 598 testing, which are standard for petroleum‑industry check valves.
Typical users include refinery engineers, petrochemical plant operators and bulk fluid transport contractors who require robust check valves. Procurement teams should confirm the exact NPS size, pressure class and any special surface‑treatment requirements with Dongying Lake Petroleum Technology. The supplier’s harbour‑tier status confirms basic verification, though no response statistics are recorded.

Importers should first obtain the valve’s material test certificate and verify compliance with API 6D and the relevant flange standards before committing to purchase. Request detailed drawings that show face‑to‑face dimensions and welding end specifications.
Agree on shipping terms such as CIF Qingdao or FOB Dongying, and clarify the expected lead‑time, especially for larger NPS sizes. Because the supplier’s response metrics are not available, secure a written production schedule and payment milestones.
Plan a third‑party pre‑shipment inspection to assess material quality, dimensional accuracy and functional operation of the swing disc. Ensure the supplier provides a packing list, commercial invoice and any required conformity documentation, such as CE or ISO certificates, for customs clearance.
