PS: We also can do according to customer's requirements.
1. DBV butterfly valve is characterized by simple structure, small volume and light weight, and it is easy to install and adjust.
The valve is widely used in the medium and low pressure pipeline.
2. Good sealing performance，corrosion resistance，high pressure and temperature resistance, smart control and safe use.
3. The unique design of triple eccentricity makes no friction between the sealing surface and extend the valve service life.
4. The elastic seal is produced by the torque.
5. The wedge design makes the valve close more and more tightly by automatic sealing function, and there’s compensation
and zero leakage between the sealing surfaces.
