Features:

  • Designed with "Auto Seat Technology"®
  • A low rated and fully guided spring allows for more consistent Set Pressures from pop to pop.
  • Consistent Set Pressures allows for repeatable use without the need for excessive repairs or resetting.
  • Open, Close, Seat and Seal™
  • Fully guided disk for the proper alignment, opening and closing, and reseating of the valve.
  • Mechanical Stop prevents wear on parts and controls valve lift.
  • Pop Action relief allows the valve to go to full lift at Set Pressure. This helps with DOT regulated applications.
  • Non-rising stems allowing valves to be installed in small areas.
  • Sour Service Trim available.
  • Additional options available to meet NACE MR0175 requirements.
  • Canadian Registration Number (CRN)
  • Additional options available to meet Conformité Européenne (CE) to PED Directive 2014/68/EU and/or ATEX Directive 2014/34/EU
