FE Petro Model “STD” Check Valve


The check valves produced by FE Petro were developed to accommodate a variety of electronic and mechanical equipment used in Line Leak Detection today. Electronic Line Leak Detectors manufactured by several companies require that the line pressure relieve to a certain pressure (in PSI) to conduct a proper leak test. This relief pressure varies depending on the requirements of the electronic equipment

  • Opens at about 40 PSI (2.8 bar)
  • Resets above 35 PSI (2.4 bar)
  • Typically used for Mechanical Line Leak Detectors (MLD) and some electronic line leak detectors (i.e., Incon, Emco Wheaton, and RJ ST)
  • Identified with Silver ID Nut.
