Trunnion Mounted Ball Valve is the result of Innovative
engineering. It embodies all the quality, Performance, value
and safety features required for critical applications.
In Trunnion Mounted Ball Valve, the
ball rotates without moving on the horizontal axis, where
as seats are floating and free to move on the same axis.
As the pressure increases the force on the seat ring by
the pressure pushes towards the ball giving ‘BIDIRECTIONAL’
sealing.
Thrust due to (Fluid Pressure + spring)
both on the upstream and downstream, pushes seat ring towards
the ball for positive sealing under all conditions.
When the valve is in closed position,
the fluid trapped in the body cavity is subjected to thermal
expansion and the valve cavity pressure increases. The
excessive pressure buildup within the valve cavity is relieved
automatically when the pressure inside exceed the spring
load on the seat.
Internal Trunnion reduces the chance
of fluid leakage to the atmosphere as in the case of external
Trunnion Mounted ball Valves.
