Product features: Metal hard-sealed butterfly valve, high-temperature and high-pressure butterfly valve, hard-sealed flanged butterfly valve. Main performance features :1 Unique structure, small and lightweight, flexible operation, labor-saving and convenient; The sealing is reliable and can achieve airtight sealing without leakage
Leak; 3. The flow characteristics tend to be linear and the adjustability is better.
Introduction to the Product Structure and Performance of Hard-sealed Butterfly Valves:
The three-eccentric hard-sealed butterfly valve series products are long-life and energy-saving butterfly valves developed by our company. The products comply with the standards JB/T8527-97(Metal-sealed Butterfly Valves) and GB/T13927-92(General Valve Pressure Test)
In accordance with the provisions of other relevant standards for valves, this product is composed of main components such as the valve body, butterfly plate, sealing ring, and transmission mechanism. Its structure is designed based on the three-dimensional eccentric principle, and it is processed with compatible elastic sealing and hard and soft multi-layer sealing
It enables the butterfly valve to reduce its torque force during operation, achieving the functions of labor-saving and energy conservation. So as to ensure the overall corrosion resistance. High-temperature resistance and anti-wear reliability.
Main performance characteristics of the two-hard-sealed butterfly valve:
1. Unique structure, compact and lightweight, flexible operation, labor-saving and convenient;
2. The sealing is reliable and can achieve airtight sealing without leakage.
3. The flow characteristics tend to be linear and the adjustability is better.
4. By adopting the three-eccentricity principle, the sealing surface is nearly zero wear, which extends the service life of the valve.
5. Wide range of applications. It can be used for media such as water, steam, oil products, air and gas.
6. It is applicable to pipelines of various media such as different temperatures and pressure grades below 6.4MPa, and is corrosion-resistant. Iii. Applications of Hard-sealed Butterfly Valve Products:
This butterfly valve is suitable for use in food, pharmaceutical, petrochemical, power plants, steel mills, industrial environmental protection water treatment and high-rise buildings. It is an ideal device for regulating flow and cutting off fluid in water supply and drainage pipelines.
