type 2: 500 mbar
type 3: 1 bar

Function: spring loaded
Operating temperature: (1)-60 °C to +130 °C

Sicherheitsventil – frei abblasend

(1) Please mind the temperature range of the gas meter!

 Max. flow rate:  at set pressure of:  
Air (0°C)27Nm3/h type 1:50mbar
CO2 (0°C)22Nm3/h type 2:500mbar
N (0°C)50Nm3/h type 3:1bar

Caution: If the pressure will exceed the above-mentioned set pressure, the safety valve will open. However, if the flow rate from the gas source exceeds the above-mentioned max. flow rate, the valve would not be able to vent the meter quickly enough.

This would built-up a pressure inside of the meter and may destroy the gas meter despite of the opened valve!
