Series 8540 End-of-Line Conservation Pressure Vacuum Breather Vent

Brand: Protectoseal Company
The Protectoseal Series 8540 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.
Features
  • Fast Inspection, Easy Maintenance
  • Maintains Accurate Pressure Settings
  • Air-Cushioned Seating
  • Automatic Condensate Drainage
  • Low-Leakage
  • Sizes Available
  • PRO-FLOW Sizing and Selection Software
