Why-dbv valve manufacturer

  Triple Eccentricity Design Features  


The stem is offset on both the X (1)and Y (2) axis of the valve'scenter line. This produces a cam一like motion.

 The third offset (3)consists of an inclined conical  profile machined into  the  valvesealing  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 seatand seal ring are  fully  engaged  torque 

 is applied in order to create a bi一directional, zero leakage,  metal-to一metal seal. Forthis reason, triple

 offset valves are often defined as "torque" seatedrather than”position” seated as in the case of resilient

 or highperformance 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.
