Abstract
A pressure reducing device having an upstream end connected to a pressurized gas source and a downstream end connected to a coupled installation. The device includes an operational fluid circuit having a pressure reducing unit configured to reduce the pressure of a pressurized gas flow to a maximum pressure P, an emergency shut-off valve and an outlet interface with a pressure capability P. The safety relief device is configured to have at least two states. A closed state where the safety relief device is inactive and the emergency shutoff valve is open, when the pressure in the fluid circuit downstream of the pressure reducing unit is lower than a predetermined pressure P. And an open state where the safety relief device is active and the emergency shutoff valve is closed, when the pressure in the fluid circuit downstream of the pressure reducing unit is higher to the predetermined pressure P.
