  1. Pruebas
  • Shell Test: 1.5 x Rated Pressure
  • Seat Test: 1.1 x Rated Pressure (Bi-directional)
  • Leakage Rate: Zero Leakage (API 598)

Technical Notes:

  • Double Eccentric Design: The shaft is offset from both the centerline of the disc and the body, reducing seat wear during operation.
  • Extended Stem: Allows the actuator to be positioned above ground while the valve body remains buried. The stem extension is sealed to prevent ingress of moisture and soil.
  • Buried Coating: The coal tar epoxy provides a durable barrier against galvanic corrosion and soil stress .
