electric flange WCB butterfly valve |
| The electric device may be used to have the type preventing explosion together outdoors. |
| Hard seal butterfly valve due to the product principle of eccentric butterfly valve is used in 3 d design, make the space of the sealing surface movement to achieve ideal, no friction, no interference with each other, together with sealing material is properly selected, so that the butterfly valve sealing, corrosion resistance, high temperature resistance and wear resistance are the reliable guarantee.Its main features are as follows: |
| 1. Small opening torque, flexible and convenient, and energy saving. |
| 2. The three-dimensional braiding structure makes the disc tighter and tighter, and its sealing performance is reliable, reaching no leakage. |
| 3. High pressure resistance, corrosion resistance, wear resistance, long service life, etc. |
