Product Description
The axis of the valve stem deviates from the center of the butterfly plate and the center of the body. The double eccentric effect enables the butterfly plate to be quickly separated from the valve seat after the valve is opened, which greatly eliminates unnecessary excessive squeezing and scratching of the butterfly plate and the valve seat, reduces the opening resistance torque, reduces wear, and improves the service life of valve. Thanks to the drastic reduction in scratches, the metal valve seat can be also used as the double eccentric butterfly valve, expanding the application of butterfly valves in the field of high-wear medium. The valve has the characteristics of corrosion resistance, non-scaling, non-aging, durability, good robustness and long service life.DN | L | flange dimensions comply with DIN2501 |
