▤ Special Notes：We also can do special material according to customer's requirements
▤ Yoke Design
DBV butterfly valve adopts the design of top flange yoke as standard ISO5211. It is more beautiful, and also convenient to assemble the actuator.
▤ Multilayer-304+graphite Sandwich Design
DBV butterfly valve adopts the design of multi-layer disc sealing ring, sealing by the inside
graphite, applied for low and middle pressure, as recycle water, swagetreatment, city building, etc.
▤ Turtle Back Disc Design
DBV butterfly valve adopts the design of turtle back disc, not only strengthening the disc to be more strong, but also making it looks very beautiful.

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.
