with  the  gland.  It  is effectively that prevent the stem 

blows out from the top.

Wafer Butterfly Valve-3

Internal Snap Ring and Bottom Cover Design

    DBV butterfly valve adopts the unique stem design. 

The  bottom  of the  stem is slotted.  Then, the snap 

ring  is  embedded to prevent the stem blow out.The

bottom  cover  plays  a  same role. This design  suits

 for the valve which is larger than four inches.

  Why Choose DBV Valve?                                                                                                                                                                                 

  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.
