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.
