Material and corrosion resistance advantages The core components (valve body, butterfly plate, valve stem) are cast using 304/316L/dual-phase stainless steel, with nickel content meeting international industry standards. They have strong resistance to intergranular corrosion and pitting corrosion, and can be adapted to various export conditions such as seawater and chemical corrosive media, meeting the complex medium requirements of different regions such as Europe, the Middle East, etc. They comply with multiple national design and manufacturing standards including API, GB, DIN, etc.
The flange connection method ensures stable connection and reliable sealing, is suitable for large-diameter export pipeline scenarios, is convenient for installation and maintenance, and reduces the after-sales operation and maintenance costs for overseas customers. The hard-sealing structure has a wider temperature tolerance range compared to the soft-sealing structure (-40℃ to 650℃ for stainless steel valve body), better erosion resistance, longer service life, and can meet the long-term operation requirements of export industrial scenarios.
Specifications and Compliance with Certifications The pipe diameter range covers DN15 to DN1200, and the pressure grades include PN10 to PN40 and Class150 to Class300. This can meet the size and pressure requirements of different export projects. We can provide certifications in accordance with international/ domestic standards such as API 609, ANSI B16.34, and GB/T 12238. In flammable and explosive scenarios, ATEX/IECEx explosion-proof certifications can be provided. In food and pharmaceutical scenarios,.
Cost and Supply Chain Advantages Compared with similar products from Europe and America, our domestic stainless steel flange hard-sealed concentric butterfly valve has a significant cost-performance advantage. Additionally, the after-sales spare parts system is well-established.
