POTA (Pressure Only To Atmosphere)
The FAV Vapor-Tight Pressure Relief Vent with Atmospheric Release is designed for pressure relief in applications that allow the release of tank vapors into the atmosphere.


The vent is a one piece body design, which is an extremely rugged weld body unit. Taller guide rods ensure that a full open valve position is obtainable. All vents utilize 
FAV Patented Counter-force Pressure Suspended Pallet and bolt in stainless steel seat and internal components.


FAV Systems Patented Counter-force Pressure Suspended Pallet conforms to the seat like no other valve on today’s market. The inflating effect of the diaphragm increases as the pressure in the vent rises. This means that when the vent is closer to its set point, the seal is at its greatest performance. Seat leakage for a 1/2 oz/sq” setting is less than 0.5 SCFH for all sizes at 90% of set point. All vents come standard with 316 Stainless Steel internal components which include; guide rod assembly, bolts and nuts, seats, and Counter-force Pressure Suspended Pallet.
