Product Description

Triple Eccentric Flange Hard Seal Butterfly Valve is eccentric metal seal structure, sealing form is metal-to-metal seal, adjustable metal sealing ring to metal seal, stainless steel plate and graphite composite plate sealing ring to metal seal.

The valve seat and the butterfly plate are almost wear-free, with the tighter the sealing function, the sealing ring is made of
stainless steel, with the dual advantages of metal hard seal and elastic seal, no matter in the case of low temperature and high temperature, it and the butterfly plate have excellent sealing performance, butterfly valve butterfly plate sealing surface is made of overlay welding cobalt-based cemented carbide, the sealing surface is wear-resistant, long service life, large size butterfly plate adopts quilted structure, high strength, large overcurrent area, small flow resistance. 

D343H-16C, D343H-10C Worm Gear Hard Seal flange butterfly valve has two-way sealing function, installation is not limited by the flow of the medium, nor affected by the spatial position, can be installed in any direction, this butterfly valve structure is unique, "switch" only need to turn the stem 90 ° can be completed, flexible operation, convenient, labor-saving, not affected by the pressure of the medium, reliable sealing performance, high temperature resistance, low temperature resistance, corrosion resistance, therefore, is widely used in the medium temperature ≤ 425 °C metallurgy, electric power, petroleum, chemical industry, air, gas, On the pipes of combustible gases and corrosive media such as water supply and drainage, there are devices for regulating the flow rate and cutting off the fluid.
