AV095

General

The relief valves in the AV095 Series are safety devices (SBV) for discharging a certain amount of gas when the pressure at the control point exceeds a given level (bubble-bursting pressure) due to any temporary occurance such as the momentary shutting of the on/off valve and/or the overheating of the gas with no flow requirement.

Discharge of the gas can, for example, avoid any intervention by blocking devices in the case of transient causes not regarding damage to the regulators. Clearly, the amount of discharged gas depends on the entity of the excess pressure in relation to the pressure setting.

Features

  • Simple design and easy maintenance
  • Can be mounted in any position
  • Safe operation
  • High response accuracy
