T40 - T-Port Valve: Multi-functional valve design, providing optimum solution for one-pig-systems

Patented tee branch valve, providing product isolation and pig catching facilities. Can also be equipped as a launching station with integrated pig changing chamber.

The T-Port valve is "open": The connection to the tank is open, station is ready for product transfer.

When the transfer is finished the pig completely pushes the residual product into the tank. The pig is stopped at the pig stop.

The T-Port valve is "closed": The connection to the tank is isolated and the piggable passage open. In this position the pig can pass through the valve and be returned to the launching station.

Typical piggable distribution system incorporating in line T-Port valves. Simple "One Pig" process is sufficient to handle multiple product inlets/destinations.

The T-Port Valve is particularly suitable for single direction pigging systems. For such applications the T-port valve provides safe and clean pigging results comparable with two pig systems, but with reduced control system expenditure: with only two positions it is possible to open the T-branch and transfer the product with minimal pressure drop and also stop the pig.

In this position the T-port valve is isolated. In the second position the pig passage is opened and the T-branch is isolated.

The sealing principle utilised in the T-port valve is the same as in our proven T41 three way valve. The main seal is manufactured from PTFE and covers the valve drum completely. Hence, no product residue remains in the piggable passage.
