3g why

  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.
