The AV095 series of release valves are safety devices which release gas in a particular volume when a pre-determined threshold pressure at the control point is reached as a result of a transitory occurrence. Units can release gas without the need for flow for occurrences such short shutdown of the starter valve and/or gas overheating, for example. The excess pressure entity determines the quantity of gas released by the pressure setting. The excess pressure. The AV095 features a simple design that can be put anywhere and no maintenance is required. It enhances operational safety and ensures high precision of the reaction.
