Import Class150-300 Cast Steel Gate Valve — Buy in Bulk from Supplier in China

The Class150-300 cast steel gate valve supplied by Wenzhou Ok Valve Manufacturing Co., Ltd is a full‑bore, metal‑sealed valve engineered for Class 150 to Class 300 pressure classes. It is forged from cast steel according to ANSI B16.34 and API 600/API 6D specifications, ensuring compliance with recognised industry standards. The design incorporates a compact body that reduces installation space while maintaining structural integrity. Manual operation is provided through a handwheel that offers smooth opening and closing of the flow path.

Typical cast‑steel gate valves of this size are supplied with ANSI‑B16.5 flanged ends in DN 50‑150, and a standard bonnet thickness of 12 mm. Standard testing includes a hydrostatic test at 1.5 times the rated pressure and a seat leakage test of 0.1 mm H₂O. The valve body is often finished with a corrosion‑resistant coating such as zinc‑rich paint, a practice that is typical for valves destined for water‑treatment plants. While the supplier lists ISO and CE certification, the exact certificate numbers should be confirmed with the factory before purchase.

Primary applications include oil and gas pipelines, water‑treatment facilities and chemical processing lines where reliable shut‑off is essential. The supplier offers flexible minimum order quantities and ships under FOB or CIF terms, with packaging designed to protect the valve during transit. Importers should verify the supplied certification documents and request a material test report to confirm compliance with the cited standards.
