Raise Face

DBV can produce valves of various connection methods,such

as RF,RTJ,BW,NPT......The Rasied Face is the most common

type used in process plant applications. Different types of 

flange faces are used as the contact surfaces to seat the

sealing gasket material



Flange ball valve



Raise face finish     

The ASME B16.5 code requires that the flange 

face (raised face and flat face) has a specific 

roughness to ensure that this surface be 

compatible with the gasket and provide a high quality seal





Turnnion Mounted Ball Valve




Full port/full bore 

Full bore 100% open according to API 6D standard. 

We also can produce reduce port







API 6D Ball Valve



Bolt&Nut

DBV ball valve adopts the standard bolts and nuts.

It could extend the valve longer service life

 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.
