L / T Port Reduce/Full Bore, Flanged End

Three way Ball Valve is available in “L” Port / “T Port to meet the service condition.

L Port BALL Valve

The Three Way “L” Port Ball Valve also called as a Diverting Valve. Also Known as a Duplex Filter Valve.

The different combinations of flow are shown in the figure.

As shown in fig – a valve member i.e. Ball – has two ports – One inlet and another outlet – Flow can be diverted to either direction. Generally at 90 deg.

The L valve can connect the center port to either side port, or disconnect all three, but it cannot connect the side ports together. L Port Valves have a ball that join two adjacent ports. Traditionally, they are used to direct flow between the Centre and one of two side ports.

T Port Ball Valve – also known as a Mixing Valve.

As shown in fig – a valve member i.e Ball – has three ports. Different flow combinations are possible as shown in the fig      

It is easy to see that a T valve can connect any pair of ports, or all three, together, but the 45 degree position which might disconnect all three leaves no margin for error. T-Port valves can also direct flow between the centre and one of two side ports.  The difference is that they have a third handle position that connects the centre to both side ports at the same time.JD Multiport 3 Way Ball valves utilize four seats to support the ball, and to provide positive shutoff at any closed port.
