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.
Oval Turtle Disc Design
DBV butterfly valve adopts the unique oval turtle
or truss structure design of the disc. It has several
advantages such as high strength, good flow
characteristics and low flow-resistance coefficient.
Up Blow-out Proof Design
DBV butterfly valve adopts the design of stepped shaft
with the gland. It is effectively that prevent the stem
blows out from the top.
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.
