1. The main features of imported butt welding butterfly valve are compact structure, light weight, easy installation, small flow resistance, large flow capacity, avoiding the impact of high temperature expansion, and light operation. There is no connecting rod and bolt in the body, which is reliable and has long service life. It can be installed in multiple stations, not affected by the flow direction of media.

2. The imported butt welding butterfly valve adopts the three eccentric structure, the butterfly plate and the valve seat contact or separate instantaneously, so as to realize zero wear and zero leakage;

3. Because the seal ring of the imported butt welding butterfly valve is completely embedded in the butterfly plate, the whole valve does not need to be removed for maintenance, so it is convenient to replace, and the maintenance cost is greatly reduced;

4. The sealing ring of imported butt welding butterfly valve adopts the sealing surface of soft and hard laminated stainless steel sheet and flexible graphite plate (graphite rubber plate, asbestos rubber plate, etc.), which has the double advantages of metal hard sealing and elastic sealing. It has excellent sealing performance under both low and high temperature conditions.

5. The conical sealing surface of the valve seat of the imported butt welding butterfly valve adopts hardfacing such as edcr-b-15, which makes the sealing surface wear-resistant, long service life, and can be opened and closed for more than 10000 times without damage.

6. The imported butt welding butterfly valve has the characteristics of high temperature resistance and corrosion resistance by selecting international first-class materials.

7. The imported butt welding butterfly valve has reliable fire resistance because it is made of refractory materials;

8. The three eccentric structure of the imported butt welding butterfly valve enables the valve to have the self-locking function. When the butterfly plate is closed to the sealing position, it can realize the self-locking immediately without the fault of the butterfly plate closing to the over position;

9. The imported butt welding butterfly valve is easy to operate, with low output torque, streamlined design of butterfly plate and low pressure loss coefficient. The imported butt welding butterfly valve is an energy-saving product;

10. The sealing valve seat of imported butt welding butterfly valve can be adjusted, which is convenient for assembly and maintenance;

11. The imported butt welding butterfly valve and pipeline are connected by welding, which is convenient for installation and use. It can be manual, electric and pneumatic to realize intelligent control.

12. The imported butt welding butterfly valve can close the cut-off medium and adjust the medium flow at will.
