    Full-port Trunnion Ball Valve Full-bore Fire-safe Anti-static Blowout Proof Stem

    Full Port Trunnion Ball Valve Full bore Forged Steel Gear Operated


    For the full bore valve, the bore diameter in the ball has the same internal diameter as the pipe, whereas a reduced bore valve has a smaller bore diameter than the internal diameter of the pipework it is on.


    The full port design ensures minimal flow resistance, pressure drop and cavitation. Full-port ball valves are used where their low flow resistance is of value such as on pump suction pipes, where a pressure drop can affect pump performance. They are also used in flows containing mixed liquids and solids where flow restrictions can cause separations in the materials causing buildups and thus reducing the flow in the pipes.


    Another reason for full-bore valves is for cleaning. It is common practice in the oil and gas industry to push a ‘pig’ through a piping system. A ‘pig’ looks like a ball that gets pushed through piping system to clean the inside of the pipes and valves. A full-ported valve is critical for this type of practice since a pig would get stuck on a reduced ported valve.


    On the other hand, reduced-port ball valves are used where pressure drop, turbulence in the flow and material characteristics are not a concern. They also have the advantages of smaller size and lower cost.
