  • 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
