Why-dbv valve manufacturer


    Triple Eccentricity Design Features  

TripleEccentricity




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.
