High Performance Metal seal Butterfly Valve
The flange type multi-layer metal hard seal butterfly valv has the following features: 1. U shaped stainless steel seal ring is used; the valve plate has certain elasticity so as to have good sealing with the butterfly plate no matter at high temperature or low temperature; 2. The valve is metal on metal line sealing valve; the sealing faces of the butterfly plate is made of stainless steel or hard alloy by buildup welding, and thus have good wearing resistant performance and long service life; 3. The butterfly plate is designed to be streamline type; the parameters of the through rod and the anti-wearing sleeve provide good sealing performance and temperature, pressure, wearing and corrosion resistant performance to the valve; 4. The connection method of the valve can be designed to be flange connection and clip connection; 5. The drive method can be manual, electric or pneumatic.
