Advantage Features
1. The sealing surface of the butterfly plate is designed as an oblique conical surface relative to the axis of the butterfly
plate, so that the sealing surface of the butterfly plate and the sealing surface of the valve seat have a certain contact angle,and both of them play a compensation role of sealing.
2. When the sealing surface of the butterfly plate is closed, the force is uniform and the pressure bearing capacity is high;
during the opening of the butterfly plate, the points of the sealing surface complete the action of leaving the sealing surface of the valve seat at the same time, which is basically non-friction and the opening torque is extremely small.
3. Various sealing structures to choose from, soft sealing (PTFE, C-TFE, G-TFE), hardened metal sheet type, integral type + hard alloy, suitable for various working conditions.
4. It can realize two-way sealing function, which can be adjusted and cut off.
In summary, the new butterfly valve has the advantages of small size, light weight, excellent cutting performance, low cost, good sealing performance and long life.
