Features: 

Professional design

When initiating the rotary opening movement the disc is off-seated after only a few 

degree of opening movement and there is very little wear and tear between seat ring and disc.

 

Combine fastness

Stainless steel seat ring is rolled into the valve body by applying special rolling technology 

when DN<1200.  Ultrasonic spray applies seal of valve body when DN>1400.                      

 

Adjust tightness

Rubber sealing ring and disc can adjust tightness or softness of sealing with clamping ring, it insures 

best performance of adjusting the compression of sealing.

 

Mail part & material 

Body, Disc: GGG50 with internal and external epoxy resin coating 

Stems: 1Cr17Ni12Mo2Ti, Stainless steel min.13%Cr 

Bushing :Bronze CuAI10Fe3
