DIN Standards Committee Heating and Ventilation Technology and their Safety

Overview

Automatic shut-off valves are valves for the opening and closing of gas pipelines. A gas safety valve according to EN 161 is designed that it opens when energized and closes automatically when de-energized. The European Standard EN 161 specifies the safety, construction and performance requirements for automatic shut-off valves for use with gas burners, gas appliances and similar use, hereafter referred to as 'valves'. This European Standard is applicable to valves with declared maximum inlet pressures up to and including 500 kPa (5 bar) of nominal connection sizes up to and including DN 250 for use with one or more fuel gases in accordance with EN 437. The European Standard EN 161 is applicable to electrically operated valves and to valves actuated by auxiliary media where the control valves for these media are actuated electrically, but not to any external electrical devices for switching the control signal or actuating energy.
