Ball valves are widely used in industries such as petroleum refining, chemical engineering, papermaking, pharmaceuticals, food, hydropower, municipal services, and steel. Among them, the anti-sulfur series ball valves are particularly suitable for long-distance natural gas pipelines with hydrogen sulfide-containing media, high impurities, and severe corrosion.
To meet the diverse needs of customers, ball valves are available in two major series: full bore and reduced bore. The full bore ball valve has an inner diameter of the channel consistent with the inner diameter of the pipeline, which not only minimizes fluid resistance but also facilitates pipeline cleaning. In contrast, the reduced bore ball valve has a fluid resistance much lower than that of a gate valve of the same diameter, and its weight is about 30% lighter than that of a ball valve of the same diameter, effectively reducing production costs and prices, and thus has been widely used.
Our ball valves come in three structures: fire-resistant, anti-static, and lockable.
When you need a reliable ball valve for critical pipeline infrastructure, Zhejiang Naibang Valves Co., Ltd. (NIPO) delivers engineered excellence. As a dedicated manufacturer with nearly 20 years of experience, we supply premium industrial flow control solutions. Our products are designed for positive shutoff, full flow capabilities, and long-lasting durability. This comprehensive range handles the rigorous demands of complex industrial pipelines. We ensure optimal system safety and efficiency across diverse applications.
Selecting the right valve requires careful consideration of operating conditions, media, and pressure requirements. We offer a structured catalog categorized by material and specific performance features. This helps engineers and procurement teams easily navigate our inventory. You can quickly find the exact solution for your unique project needs.
Our stainless steel ball valves are manufactured from premium 304 and 316 grades. They offer exceptional corrosion resistance and structural durability. These units are the ideal choice for harsh operating environments and chemical processing plants. They excel in applications where media purity and resistance to aggressive fluids are paramount.
For systems operating under extreme pipeline stress, our high-pressure models maintain absolute structural integrity. They are designed to ensure zero leakage even under severe conditions. Robust options like our trunnion-mounted flanged ball valves provide safe isolation for critical networks. Additionally, we offer API 6D floating flange ball valves for reliable performance in demanding oil and gas applications.
Beyond our standard product line, NIPO possesses a strong capability to produce custom flow control solutions. Backed by our dedicated R&D team, we manufacture specialized valves according to your specific engineering drawings. This ensures a perfect fit for unique project requirements and specialized infrastructure.
