Double Eccentric Hard Sealed Butterfly Valve PN10/PN16
Core Advantages of Double Eccentric Hard Sealed Design
The Double Eccentric Hard Sealed Butterfly Valve PN10/PN16 integrates the advantages of double eccentric technology and hard sealing process, solving the pain points of traditional butterfly valves such as poor sealing, easy wear and short service life. Its core design highlights are concentrated in the following aspects, ensuring stable operation in harsh industrial environments and reducing maintenance costs for customers.
1. Advanced Double Eccentric Structure: Reduce Wear, Extend Service Life
Different from the traditional concentric butterfly valve, this product adopts a double eccentric design—eccentricity between the valve shaft and the valve seat center, and eccentricity between the valve shaft and the butterfly plate center. This unique structure enables the butterfly plate to quickly disengage from the valve seat when opening, avoiding friction between the butterfly plate and the valve seat during the opening and closing process. Compared with ordinary butterfly valves, the wear of the valve seat and butterfly plate is reduced by more than 60%, greatly extending the service life of the valve and ensuring long-term stable operation even under frequent opening and closing conditions.
2. High-Performance Hard Sealing: Zero Leakage, Strong Adaptability
The hard sealing design is the core highlight of this valve. The valve seat and butterfly plate are made of high-hardness alloy materials (optional stainless steel, cemented carbide, etc.), which have excellent wear resistance, corrosion resistance and high-temperature resistance. After precision machining and strict testing, the sealing performance reaches the zero-leakage standard, effectively preventing fluid leakage and avoiding economic losses and safety hazards caused by leakage. Whether it is clean water, viscous oil or corrosive natural gas, the hard sealing structure can maintain stable sealing performance, adapting to the diverse fluid characteristics of different industries.
3. PN10/PN16 Pressure Rating: Suitable for Most Industrial Scenarios
The valve is designed with PN10/PN16 pressure levels, which perfectly matches the pressure requirements of most industrial fluid transmission systems. It can stably operate under the working pressure of 1.0MPa-1.6MPa, and is widely applicable to water supply and drainage projects, petroleum refining, natural gas transmission, chemical industry, power generation and other fields. The reasonable pressure design not only ensures the safety and reliability of the valve, but also reduces the cost of matching with the pipeline system, improving the overall cost performance of the equipment.

Applicable Scenarios: Wide Application in Key Industries
With its excellent performance and flexible configuration, the Double Eccentric Hard Sealed Butterfly Valve is widely used in various industrial fields, providing reliable fluid control solutions for customers around the world:
1. Water Supply & Drainage Industry
Suitable for urban water supply, sewage treatment, industrial circulating water and other systems. The hard sealing structure can resist the corrosion of impurities and harmful substances in the sewage, and the zero-leakage performance ensures the safety of water transmission. The double eccentric design makes the opening and closing light, suitable for large-flow water control scenarios.
2. Petroleum & Chemical Industry
Applicable to the transmission of crude oil, refined oil, chemical solvents and other media. The high-hardness sealing material can resist the wear and corrosion of petroleum and chemical media, and the PN10/PN16 pressure rating can adapt to the pressure requirements of petroleum pipeline transmission, ensuring stable operation in harsh working environments.
3. Natural Gas Industry
Used in natural gas gathering, transmission and distribution systems. The hard sealing performance of zero leakage effectively prevents natural gas leakage, avoiding safety hazards such as explosion and fire. The valve has good low-temperature resistance, which can adapt to the low-temperature environment of natural gas transmission in cold regions.
4. Other Industrial Fields
It is also widely used in power generation, metallurgy, food processing and other industries, providing efficient and reliable fluid control support for various production links. Whether it is high-pressure, high-temperature or corrosive working conditions, this valve can show excellent performance.
