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.

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

performance products.
