Product Details
Unique Plum Pin Design
DBV butterfly valve adopts the plum pin design, which
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.
Why Choose DBV Valve？
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.
