Every valve in DBV with clear typecasting and smooth sealing

 to ensure excellent sealing. Clear the valves very carefully in

 every details and the valve bore


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

Why-dbv valve manufacturer

  Triple Eccentricity Design Features  

 TripleEccentricity 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.
