The eccentric butterfly valve adopting a double eccentric structure design, it has the functions of intercepting, connecting, and regulating flow, which can meet the diverse needs of urban water supply and drainage, building fire protection, metallurgical hydropower and other system pipelines. Its sealing surface is welded with stainless steel material, combined with a dual sealing ring structure, which effectively solves the problem of shaft hole leakage while improving corrosion resistance. The product achieves or exceeds the national standard level in performance indicators through the application of flow field simulation and stress measurement technology.

The double eccentric butterfly valves are suitable for room temperature clean water, cooling water, circulating water systems, as well as municipal water supply, building pipelines, fire protection pipelines, etc. They are generally suitable for applications with pressure levels of PN1.0-PN1.6MPa.
Q1 What is the manufacturing standard for this eccentric butterfly valve?
The valve is manufactured in strict accordance with the EN593 standard, utilizing precision investment casting workmanship to ensure superior structural strength and performance.
Q2 How does the double eccentric structure reduce seat wear?
The valve stem axis is offset from both the sealing surface and the pipeline center. This allows the butterfly disc to detach immediately upon opening and contact the seat only at the moment of closing, minimizing friction and extending service life.
Q3 Does the valve support bidirectional sealing?
Yes, this eccentric butterfly valve supports bidirectional sealing capability, achieving a zero leakage grade (up to ANSI Class VI) under designated operating pressures.
Q4 What are the allowable operating temperatures and pressure ratings?
The standard configuration operates within a temperature range of -20°C < T < 120°C and is typically suitable for working pressures ranging from PN1.0 to PN1.6 MPa.
Q5 What primary application scenarios is this valve suitable for?
It is widely used in urban water supply and drainage, circulating and cooling water systems, building fire protection pipelines, and metallurgical or hydropower piping networks.
Q6 How are the valves packaged for international delivery?
All products are packed using standard export wooden cases to ensure safe, damage-free transport during long-distance shipping.
