T09 - T-Ring valve with three functions: product diversion, isolation valve and pig catching station
I.S.T. T-ring valve T09 for use in the chemical industry
This I.S.T. T-ring valve takes on 3 jobs at once: it acts as a branch in pigging system pipelines, incorporates a product isolation valve and also "catches" and "launches" pigs.
It can be used either as an independent station or integrated in a distribution assembly. The horizontal plane can be pigged without pockets when the valve is closed. The vertical port can be closed with the ring-shaped seal when necessary.
Pressure balanced seal design provides effortless movement of the valve ring, using only a small pneumatic cylinder. There is only minimal pressure drop when the product flow is diverted.
Advantages
- Three functions with one valve
- Only minimal pressure drop
- Excellent durable original I.S.T. quality
- Suitable for Ex-areas
- No residual product left in the pipeline
- Pneumatic actuation
- Compact size
