Features

  • Tefl on seats mated with the stainless steel multiple crown rings which provide a reliable sealing. The triple crown sealing rings are located at slightly diff erent heights in order to provide compound sealing ability with the mating tefl on ring.
  • Special extra lift, pop-open feature in order to provide a high relief capacity.
  • A four-wing guided, stainless steel upper seat provides an excellent guidance for the high lift and reseating action.
  • A spring and seat design which provides for a concentric and axial spring force, loads the upper seat uniformly and maintains a tight seal.
  • All relief valves come with an installation tag and cable wire. Each valve’s identifi cation tag has information regarding the catalogue number, month and year of manufacture, set pressure, inlet pipe size and capacity for AIR in units of SCFM. The tag is fastened with drive rivets for security.
  • Relief valves are subject to 100% factory testing through three separate test sequences to verify quality and set pressure before being factory sealed for security.
