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

This cast steel gate valve features an OS&Y design with a bolted bonnet and pressure-sealed construction, enabling visual stem positioning and reliable leak prevention under high-pressure conditions. The solid wedge mechanism ensures consistent sealing, while the back-seating feature allows for stem packing replacement without interrupting pipeline flow. The valve is constructed from cast steel to withstand abrasive and corrosive media in industrial systems.

The body material conforms to standard cast steel grades used in pressure piping, typically ASTM A216 WCB for general service or equivalent. The internal components are designed for either flexible or split wedge configurations, depending on operating temperature and fluid type. Typical operating pressures range from Class 150 to Class 2500, with temperature limits up to 425°C for WCB material. Surface finishes and sealing surfaces follow common industry tolerances for gate valves in oil, gas, and water systems.

These valves are commonly purchased by engineering firms, pipeline operators, and water treatment facilities requiring durable isolation valves for critical service. Packaging includes protective caps on flanges, wooden crate reinforcement, and anti-rust coatings. Trade terms offered include FOB and CIF, with minimum order quantities flexible based on project scale. Buyers should confirm pressure ratings and material certifications directly with the supplier before shipment.

Zhejiang Vango Valve Manufacture Co., Ltd. is based in the Dongfang Industry Zone, Oubei, Wenzhou, Zhejiang, China. The company operates as an imported supplier with harbor-level trust verification, indicating presence in export logistics channels. The listing does not specify years in operation, workforce size, or client names, and response metrics show no recorded activity. Production focus appears limited to cast steel gate valves with standard industrial configurations.

No certifications such as ISO or SGS are confirmed in the source data, and no factory audits or quality control processes are described. The supplier does not list engineering capabilities, in-house testing facilities, or custom design services. Buyers should treat this as a basic export-oriented manufacturer without public-facing technical documentation or traceable compliance records.
