Series 8540G End-of-Line Pressure/Vacuum Breather Vent

The Protectoseal Series 8540G Improved Performance End-of-Line Pressure Vacuum Conservation Vent provides both pressure and vacuum relief to maintain tank's vapor space within safe operating parameters. 

Vent settings minimize loss of product. Under pressure venting conditions, tank vapors are expelled to atmosphere. 

The new Series 8540G provides quicker pressure pallet lift and improved flow performance at low overpressures just above the relief set point. 

This provides the benefit of higher flows at lower overpressures which can be beneficial in storage tank vapor control schemes requiring tight operating bands with the tank's emergency relief vents, tank blanketing valves and other associated devices in the vapor control system.
