Threaded Ball Valves

A ball valve is a type of valve that opens and closes by rotating the ball around the centerline of the valve body. In piping systems, ball valves are primarily used to shut off, distribute, and change the direction of media flow. Two-piece ball valves and three-piece ball valves are modern valve designs that have been widely adopted in recent years.

Features:

● Nominal Diameter: DN8–DN100
● Nominal Pressure: PN10–PN25
● Manufacturing Standards: GB, DIN, API, ANSI, JIS, etc.
● Valve Body Material: Stainless steel
● Applications: Widely used in sectors such as petroleum, chemicals, water conservancy, power generation, pharmaceuticals, and food processing.

Q: What type of company are you?: A: We are an integrated manufacturer and trader (industrial and trading).

Q: What types of valves do you produce?: A: 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.

Q: What are the common materials used for your valves?: A: 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.

Q: In which industries and applications are your products mainly used?: A: Our valves are suitable for a wide range of applications, including petroleum, chemical, natural gas, industrial water treatment, municipal water supply and drainage, HVAC engineering, pharmaceuticals, food & beverage, dairy, and many other fluid control systems. They are compatible with most conventional industrial and civil pipeline projects.
