One-piece Yoke Design
DBV butterfly valve adopts the design of one piece
yoke. It is more beautiful than normal valves. It is also
convenient to assemble the actuator.
Fully Metal to Metal Design
DBV butterfly valve adopts the design of fully metal. The
alloy steel is overlayed on the sealing surface, which solves
the problems of hard working conditions, such as high
pressure, low temperature and high temperature effectively.
Renewable Seat &Seal Ring Design
DBV butterfly valve adopts the design of renewable seat and
seal Ring. This design makes the valve cost lowest. If the valve
has the leakage caused by the seal ring &seat , changing the
seal ring&seat could solve the leakage.
Triple Eccentricity Design Features
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
