The difference between double seal valve and shut-off valve

The valve can completely cut off the circulation of the medium and it is less prone to leakage.

The main advantage of the two-seater valve spool is the force balance structure, allowing a large pressure difference.


The disadvantage of the two-seat sanitary valve is that the two sealing surfaces cannot be in good contact at the same time, which easily causes leakage. If artificially forced to cut off in the pipeline, the effect is not good, cut off
