Outer Trunnion Ball
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
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.
