Yoke Design

DBV butterfly valve adopts the design of yoke.  

It is more beautiful,and also convenient to assemble the actuator. 

Our yoke is made by one-pcs casting, with anti-broken hardness. 


Multi-layer Design

DBV butterfly valve adopts the design of  multi-layer disc sealing ring, 

sealing by the inside graphite, applied for low and middle pressure, 

as recycle water, swage treatment, city building, etc.

3g why

  Triple Eccentricity Design Features  

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  


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.
