A trunnion-mounted ball valve supports the ball at its rotational axis rather than allowing line pressure to move it against a downstream seat. This arrangement is often considered for larger pipeline valves and duties where operating torque deserves particular attention.
Farpro’s cast steel range includes the Q347F and Q47Ni models below. Their product pages show the available construction and dimensions, making it easier to compare options for a new installation or an existing line.

A Supported Ball, a Different Seat Arrangement
With the ball held in position, the seats provide the sealing contact around it. Supporting the ball changes the loads acting through the valve and can help manage operating torque as valve size and pressure increase.
That does not mean every trunnion valve has the same seats, bore or pressure rating. The model’s materials and construction remain important, particularly where temperature, corrosion or frequent operation influence the choice.
The Q347F cast steel model uses gear operation for manual isolation. If you are comparing it with a injap bola terapung, start with the line conditions and how the valve will be operated, then compare the individual specifications.
