500X Pressure Relief or Sustaining Valve instantly opens when the pressure in the pipeline exceeds the preset safe level, thus relieving excessive pressure from the pipeline. When the pressure returns to normal, the valve closes slowly, at an adjustable speed. The valve also can be used to sustain upstream pressure to a preset pressure value.
