830 Series Pressure & Vacuum Relief Vent

Brand: Protectoseal Company
The Protectoseal Series No. 830 Combination Conservation Vent and Flame Arrester is designed to provide 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.

Also serves as an End-of-Line Flame Arrester to protect tank’s vapor space from external sources of ignition.
Features
  • Certified flow curves validating flow characteristics of unit
  • Certified test report verifying specified settings and leakage performance
  • “Air-cushion” pallet design for low leakage performance of no more than 1 SCFH at 90% of the set pressure
  • Removable and interchangeable element(s) facilitates inspection and maintenance
  • Swing-bolt design permits easy access to arrester element
  • Unit and associated weights serialized for ease in identification
  • Automatic condensate drainage design to mitigate freezing, binding and clogging
