Description
In liquid seal valves, a liquid provides the enclosure against flow through the vent until over pressure or over vaccum occurs.
The physical properties of the sealing liquid usually are such that it has a very low freezing point as well as a high boiling point. In addition, the sealing liquid should not contaminate the storage tank contents nor, in turn, be contaminated by the thank contents.
Size : 100 mm N.B. to 300 mm N.B
The liquid seal PV valves is heavy units designed for large flow capacities. It employs two weight bells, the mouths of which are normally submerged in the sealing liquid. Pressure or vaccum relief is affected when the excess pressure or vaccum rises the respective bell out of the liquid and breaks the seal. The sealing liquid remains in one area.
