Unique Plum Pin Design


Adopts  the  plum pin design,  which DBV butterfly valve

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

advantages  such  as   high   strength,   good  flow truss  structure design of the disc. 

It has several characteristics and low flow-resistance coefficient. 








Why-dbv valve manufacturer                                                                   

  Triple Eccentricity Design Features  

 Triple Offset Butterfly Valve 





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  

 Industrial triple offset butterfly valve







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.
