The BASE® safety valve is a mechanical overpressure control device that automatically intervenes when abnormal pressure conditions occur inside the silo. The valve body and closing discs (overpressure and underpressure) are made of painted steel with rubber gasket. The protection cap is made of stainless steel. The safety valve is mounted on the silo through a flanged connection, to be welded on the silo itself.

USAGE

The safety valve is normally installed on sealed tanks for containing dusty materials. If the default setting remains within the desired limits, the three springs will keep the two discs hermetically closed. On the other hand, when there is an increase in pressure inside the silo, the overpressure disc lifts up to let the excess air out. When the pressure decreases, the underpressure disc opens allowing the external air to enter and re-establish the initial pressure inside the silo.

BENEFITS

  • Ease of installation
  • Reduced maintenance costs
  • Reliability over time
