Unique Plum Pin Design
Adopts the plum pin design, which DBV butterfly valve
is different from traditional pin design. As we all know,
traditional pin is straight to the stem, but the plum pin is
tilted to the stem. From the aspect of application, the plum
pin could afford higher pressure and larger diameter.
Standard Bolts & Nuts
DBV ball valve adopts the standard bolts and nuts. It could extend the
valve longer service life.
Triple Eccentricity Design Features
The stem is offset on both the X (1)and Y (2) axis of the valve's
center line. This produces a cam一like motion. The third offset (3)
consists of an inclined conical profile machined into the valve
sealing surface. This allows rotary engagement and disengagement
of the seat and seal ring without interference. All rubbing
between seat and seal ring is thereby eliminated. Once the seat
and seal ring are fully engaged torque is applied in order to
create a bi一directional, zero leakage, metal-to一metal seal. For
this reason, triple offset valves are often defined as "torque" seated
rather than”position” seated as in the case of resilient or high performance products.
Multi-layer disc sealing ring
Multi-layer disc sealing ring adopts ss304 and graphite laminated, sealing
by the inside graphite, applied for low and middle pressure, as recycle water,
swage treatment, city building, etc.

Test Pressure (Mpa)
Test Pressure (Mpa)
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.
