Zhejiang Shengwei Valve Co., Ltd. is a pipeline supporting valve enterprise specializing in valve design, research and development, manufacturing, sales and service. Its affiliated enterprise is Chongqing Jinxiang Valve Co., Ltd. We specialize in producing threaded gate valves, globe valves, check valves, ball valves, strainers/filters, and more. We can also manufacture non‑standard products according to customer requirements. Our valves are available in three pressure‑rating grades to suit different pipeline working conditions: Light‑duty PN10, Medium‑duty PN16, and Heavy‑duty PN25. The higher the grade, the greater the wall thickness, pressure‑bearing capacity, and structural stability. Customers can select the appropriate grade based on their project’s pipeline pressure and operating environment.
We offer 201 stainless steel, 304 stainless steel, and 316 stainless steel to meet different anti‑corrosion, weather‑resistance, and media requirements.
● 201 is cost‑effective and suitable for general residential use, HVAC, and clean water applications.
● 304 offers good corrosion resistance and stability, widely used in water treatment, municipal projects, and general chemical scenarios.
● 316 provides stronger acid and alkali resistance, ideal for demanding conditions in chemical, pharmaceutical, and fluid‑handling systems with complex media.
All raw materials are inspected upon incoming receipt. The standard working temperature range is 0°C to 80°C, and we also support custom material specifications upon request.
