BallValvewithGreaseInjection



Grease Injection Design On Stem

 DBV trunnion ball valve (DN≥150,NPS6)adopts the design of grease

injection.  It  is effectively avoiding the leakage caused by the stem O

rings are unexpectedly damaged.






SoftSeatBallValve


Grease Injection Design On Seat

 

DBV trunnion ball valve (DN≥150,NPS6)adopts the design of grease

injection.  It  is effectively avoiding the leakage caused by the seat rings

are unexpectedly damaged.






BallValvewithBlowoffValve


Blow-off Design



When the valve is closed, the pressure in the body cavity will be

accumulated , and the pressure is removed by opening the blow-off

valve. 






BallValvewithDrainValve



Drain Valve Design 


The seal of the trunnion ball valve is achieved by the floating seat.When

the waste of the inner cavity is removed through drain valve, the

pressure will exist between the inlet and outlet end of the compression

seat, and it is easier to achieve the sealing performance.





FlangedBallValve





Flange Connection Design

RTJ end is usually used to high pressure valve. DBV make it according to customers'

requirement.

 Outer Trunnion Ball 

OuterTrunnionBall

The trunnion ball is the standard deisign for ball valves, which guarantees an

 easy assembling into valve, a wide surface for washers (reducing friction and

 torque).The ball can only turn around its own axe (trunnion axe) and sealing

 is guaranteed by the axial movement of the seats for springs or inline pressure.The

trunnion design is suggested for medium and big dimensions and enables to avoid

 high torque during opening or closing phase with inline pressure. The critical issue

 for these products consists in the poor material between the bore and the washer

 area it occurs an easier deformation of the ball for high pressure and consequently

 leakage between seats and ball.




 Inner Trunnion Ball 

InnerTrunnionBall


This structure is suitable for small size valve or higher pressure

environment. With simple design and convenient maching, this

ball guarantees a stronger resistance of the ball than the outer,

and so less deformation in high pressure condition reducing the

risk of leakage between ball and seats. However, it's critical for

the valve assembling especially for big dimensions; limited space

for washers.
