Direct Acting High Flow Vent

  • The Series 5000 EPRV provides high reliving flow rates suitable for emergency venting applications in a robust and reliable direct acting design.
  • Self resetting action ensures continued leak-free performance after venting activity without operator intervention.

Compound Lever Design

  • The compound lever of the 20 and 24” EPRVs reduces total vent weight, and provides a compact operating envelope.
  • Compound-lever EPRVs achieve full-lift at a lower overpressure than comparable single-lever designs.

Wide array of set pressures

  • Standard relief pressures from 1 to 16 ozsi, in 1 ozsi increments, with up to 32 ozsi available on the 20” and 24” sizes.

Composite eFKM seals

  • The standard high performance composite seal provides bubble-tight sealing to over 90% of set pressure, exceeding API 2000 leak test requirements.
  • The Series 5000 is ready for sour service out of the box with eFKM Seals.

Manway Access

  • The covers of the 20 and 24” EPRV’s can be locked open to provide manway access.


  • Standard EPRVs in all sizes and bolt patterns are stocked for quick delivery.
