    Flange 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.

3g why dbv valve

  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 bal.





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.
