Valve Details



 Body design

Axial flow structure and accurate flowing passage enables little pressure loss ,stable medium flowing,and non cavitation erosion.


 Disc design

The special structure and surface treatment of the disc carrier and pin eliminates the phenomenon of valve sticking.It can close and open evenly to avoid the common defects of disc can not stay in the center of sealing  position because of the gravity of disc. So the valve has wonderful and lasting sealing effect.


 Guiding Part 

The guided spring loaded poppet system maximizes efficiency and reduces water hammer while preventing flow reversal. Designed for flanged installation, this valve will operate well in any position.


 Raise Face

DBV can produce valves with various end connection,such as RF,RTJ,BW,NPT,etc.The Rasied Face is the most common type used in process plant applications.
