Internal Snap Ring and Bottom Cover Design

DBV butterfly valve adopts the unique stem design. The  bottom  of

the stem is slotted. The ring  is  embedded to prevent the stem blow 

out. Then, the snap bottom  cover  plays  a  same role. This design

suits for the valve which is larger than four inches.

3g why

  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.
