It is mainly used for installation on low-pressure gas system pipelines of ships. When the gas supply pressure in the ship's pipeline experiences underpressure or overpressure, the vent cock at the end of the sounding self-closing valve will automatically pop out, achieving automatic closure. Manual restart is required when rebooting.
