Import Check Valve — Buy in Bulk from Supplier in China

Shanghai Astain Valve Co., Ltd provides wafer‑type and vertical‑lift check valves constructed from WCB and F51 stainless steel. The valves cover a pressure range from 150 lb to 2 500 lb, addressing diverse process requirements. Sizes are available from NPS ½ to 32 in, allowing flexible fit into a wide array of pipelines. The compact wafer design reduces installation space while the vertical lift mechanism ensures smooth operation under varying pressures.

WCB stainless steel offers excellent corrosion resistance in aggressive media, and F51 stainless steel adds strength for high‑temperature service, both complying with ASTM A182 standards. Typical industry pressure classes for these valves are Class 150 to Class 600, matching the disclosed pressure range. The valves conform to standard flange dimensions per ASME B16.5 and feature a full bore flow path for minimal pressure loss. Temperature service limits are generally - 30 °C to 150 °C, typical for stainless‑steel check valves.

Key buyers are oil‑and‑gas operators, water‑treatment plants and chemical processors that require reliable backflow protection. Trade options include FOB or CIF, but exact incoterms and payment terms should be verified with the supplier before order. MOQ is flexible; interested parties should request a quotation to determine the appropriate volume. Pre‑shipment inspection can be organised under ISO‑based quality plans.
