Pressure Vacuum Relief Vents – Pipe-away

pvrvThe breather valve model 1000 series is part of FNC’s line of high performance pressure-vacuum relief valves. It is designed to provide pressure and vacuum relief to maintain tank vapor space within safe operating parameters in a closed pipe-away design.

  • Advanced materials for seat and pallet provide superior resistance to corrosion, chemical attack, liquid and vapor adhesion, temperature extremes and sticking due to valve seat freeze
  • Standard test for compliance with API2000 and API 527 (1 SCFH at 90% of set pressure)
  • Stainless steel seat and pallet
  • Proximity switch option, to detect open and closed position of PVRVs
