Use:
Double eccentric double flanged metal seal butterfly valve is my company engineering and technical personnel with reference to the United States ANSIWWAC504 standard design and development of new products, widely absorbs the domestic and foreign advanced experience, research and development
The new products, its performance has been in the domestic and foreign advanced water goods, the valve has reasonable structure, reliable sealing tightness, small flow resistance, high pressure difference, driving flexible and labor-saving, double life. Extensive
For low voltage, medium voltage condition, is used in water supply and drainage, metallurgy, petroleum, chemical industry, electric power industry pipeline for truncated or regulating media flow with.
Performance characteristics:
1, valve with eccentric and inclined with conical seat sealing side, using the butterfly board oscillation tightly sealed, so the sealing surface friction resistance is small, closed with the more closed more tightly, the sealing performance
Reliable, secure cover opening is fully disengaged, ensure the sealing surface is not damaged.
In 2, double eccentric butterfly valve special geometry, so that in the case without dismantling the valve, the valve is opened to replace the sealing ring, to extend the service life of the valve.
In 3, double eccentric butterfly valve structure to ensure that in the condition of high pressure under normal use.
In 4, the butterfly valve according to the requirements of applicable medium, selection of different materials to ensure the sealing surface, sealing surface wear resistance, erosion resistance, corrosion resistance, long service life.
