OEM Eccentric Butterfly Valve PN16 Soft Sealing Suppliers, Manufacturers
Product Description
Featuring a double-eccentric structural design, the eccentric butterfly valve integrates shut-off, connection, and flow regulation functionalities, making it well-suited for meeting the versatile requirements of pipeline systems in urban water supply and drainage, building fire protection, metallurgical hydropower, and other industrial sectors. Its sealing surface is fabricated with stainless steel welding technology and paired with a dual-seal ring configuration, which not only resolves shaft hole leakage issues effectively but also enhances corrosion resistance. By leveraging flow field simulation and stress measurement technologies, the product’s performance metrics meet or exceed national standard requirements.

The valve is manufactured in strict compliance with the EN593 standard using high-precision investment casting workmanship.
The double-eccentric structure significantly reduces friction between the disc and seat during operation, extending overall service life by 30-50% compared to standard concentric butterfly valves.
Yes, it features a bidirectional sealing direction and achieves a zero-leakage sealing grade, effectively eliminating air and water leaks.
They are widely applied in low-to-medium pressure systems (PN1.0–PN1.6MPa) handling clean water, cooling water, municipal water supply, building piping networks, and fire protection systems.
Body options include Ductile Iron and Carbon Steel (often combined with SS304), while valve seats are available in EPDM, Hypalon, PTFE, Fluororubber, and Abrasion-Resistant Rubber depending on operating temperatures.
All products are packed in standard export wooden cases to ensure security and durability during long-distance transportation.
