Function
The Prism Vapor-Tight Model POPA Pressure Relief Vent with Pipe-away Construction is designed for pressure relief in applications that require hazardous tank vapors to be piped away and not released into the atmosphere.
Construction
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 Prism’s patented Counter-force Pressure Suspended Pallet and bolt in stainless steel seat and internal components.
Special Features
Prism’s 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. Also multiple bolt lids ensure 100% sealing of the vent body assembly. 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.
