Gate valve

The gate valve offered by China Yongyi Valve Group Co., Ltd is a steel‑body valve designed for precise flow control in industrial pipelines. It is supplied in nominal diameters from DN10 up to DN1000 (3/8"‑40) and is rated for pressures between PN1.6 and PN42.0 MPa (150‑2500 lb). The body materials listed are A105, LF2, F5 and F11, providing corrosion resistance for water, oil and chemical services. The design complies with recognised international standards, ensuring suitability for power plants, refineries and water‑treatment facilities.

Typical gate‑valve designs use a forged steel body with a soft seat material such as PTFE or elastomer to achieve tight shut‑off. Standard end‑connection options include flanged, threaded or butt‑welded fittings, allowing integration into existing piping. Industry practice sets the operating temperature range from - 30 °C to +250 °C for the listed grades, and a leakage class of III (or better) is common. These characteristics give the valve durability in high‑pressure and chemically aggressive environments.

Customers such as oil‑field contractors, municipal water utilities and chemical manufacturers typically source this valve for isolation and throttling tasks. While the listing notes flexible trade options including FOB and CIF, buyers should confirm minimum order quantities and payment conditions directly with the supplier. The supplier’s harbour‑tier verification and imported status indicate a willingness to engage in international transactions, but exact lead times must be verified before placing an order.

China Yongyi Valve Group Co., Ltd is located in the Sanqiao Industrial Zone, Wenzhou, Zhejiang, China (postal code 325105). The company is listed as an imported supplier with a harbour‑tier trust rating, indicating that it has passed basic verification checks on the platform. However, the response rate is recorded as 0.00 and the average response time is zero, suggesting that communication may be limited and should be confirmed directly.

The company’s current listing focuses on gate valves fabricated from A105, LF2, F5 and F11 steel grades for industrial fluid‑control applications. No information is provided regarding minimum order quantities, pricing structures, lead‑time estimates or specific certification documents, so buyers need to request those details from the supplier before finalising a purchase.
