The disc of the tri-eccentric hard seal butterfly valve is installed in the diameter direction of the pipeline. In the butterfly valve body cylindrical channel, disc shaped disc around the axis of rotation, rotation Angle between 0°~90°, rotation to 90°, the valve is fully open. The characteristics of the new high life stainless steel butterfly valve and the problems in the use of the butterfly valve.
The tri-eccentric hard seal butterfly valve is widely used in metallurgy, electric power, petrochemical industry, water supply and drainage, municipal construction and other industrial pipelines where the medium temperature is no more than 425℃, for regulating the flow and cutting off the fluid.
Pneumatic tri-eccentric hard seal butterfly valve is based on the two -eccentric hard seal butterfly valve to generate an angle (the sealing surface is an inclined cone), thus forming the tri-eccentric hard seal butterfly valve . The structure has no mechanical wear and scratch in the process of opening and closing , small closing torque , good cutting performance and long service lige , as well as two functions of adjustment and cutting.
This Pneumatic tri-eccentric hard seal butterfly valve is DN800 , for air application , its function for cut-off air course. It is for one chemical industry in Southeast of China.
The valve body is WCB , pressure is DIN 0.6 Mpa , working temperature is -60 to 200 °C
The max size for Pneumatic tri-eccentric hard seal butterfly valve BCST can make is DN 2000.
If you have any special requirement , we can also make based on your detail.
