high performance butterfly valve manufacturerFlange face finish            

The ASME B16.5 code requires that the flange face(raised face and flat face) has 
a specific roughness to ensure that this surface be compatible with the gasket and
provide a high quality seal.

DBV ball valve adopts the standard bolts and nuts. It could extend the

valve longer service life.

Triple Eccentricity Design Features 

TripleEccentricityThe 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,  Sealingring
sealing by the inside graphite, applied for low and middle pressure,
as recycle water, swage treatment, city building, etc.
