The electric butterfly valve has elastic function and butterfly valve function. The characteristics of metal butterfly valve of electric butterfly valve are as follows:
1. Its characteristic line can be designed as an ideal curve with nonlinear characteristics.
2. The stiffness changes with the load, making the butterfly valve device have ideal characteristics.
3. Be able to bear axial and radial loads and transmit torque.
4. By adjusting the internal pressure, different bearing capacities can be obtained to meet the needs of various loads.
5. Light weight, long service life, high vibration isolation frequency and good sound insulation performance.
6. Small installation space and convenient replacement.
