T-port valve

The T-port valve integrates a T-shape discharge into the pigging line and at the same time separates the rest of the pigging line. With these two features a one pig system can be applied; this offers the advantage of easier installation, operation and automation. The T-port valve's seal principle has been well-proven for years. Available sizes are DN 25 up to DN 300 (1“ up to 12“).
Benfits
- Closed and piggable to one side
- Automatic or manual operation
Functions
In its initial state the T-branch is locked and the piggable passage is free. On switching the valve the pipeline part facing away from product is locked through a 90° turn of the cylinder. At the same time the T-branch opens and a pig catcher is turned into the pipeline. This T-branch now connects the pigging line with the discharge line through the cylinder so that the product can be transferred now. To terminate the transfer, a pig empties the pipeline up to the pig catch unit and the valve is closed again by turning, the separated part of the pipeline is opened again.
Should the product simultaneously be transferred to various discharges, the valve can be set up in a way that the rear pipeline is not separated.
This valve is often used for filling and emptying of tanks.
Options

- Heating
