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-dbv valve manufacturer

    Triple Eccentricity Design Features  

The stem is offset on both the X (1)and Y (2) axis of the valve's center line. TripleEccentricity

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.
