D343F/H tri-eccentric multi-level hard seal butterfly valve，Hard seal butterfly valveD343F/H tri-eccentric multi-level hard seal butterfly valve

Product Overview

D343F, D343H type three eccentric multi-level hard seal butterfly valve long life, energy saving butterfly valve. Its structure adopts three dimensional eccentric principle design, the valve seat adopts hard and soft seal compatible multi-level structure, exquisite processing, advanced technology. This product is composed of valve body, butterfly plate, multi-level valve seat, valve stem, transmission mechanism and other main components. Widely used in metallurgy, electric power, petroleum, chemical industry, air, gas, flammable gas and water supply and drainage of corrosive media pipeline.

Features of structure

Because the butterfly valve of this product is designed by the principle of three-dimensional eccentricity, the space movement trajectory of the sealing surface reaches the ideal, the sealing surface has no friction between each other, no interference, and the sealing material is properly selected, so that the sealing, corrosion resistance, high temperature resistance and wear resistance of the butterfly valve have been reliably guaranteed. Its main features are as follows:

1, small opening torque, flexible and convenient, saving energy;

2, three-dimensional eccentric structure, so that the butterfly plate is more closed, the sealing performance is reliable, to achieve no leakage;

3, high pressure resistance, corrosion resistance, wear resistance, long service life, etc.
