DIN EN 16304:2013-05

An automatic vent valve in accordance with DIN EN 16304 is designed so it closes when energised and opens automatically when de-energised. It opens or closes automatically and controls the inlet, flow rate or outlet of gases in the course of a gas pipe. The European Standard DIN EN 16304 specifies the safety, construction and performance requirements for automatic vent valves for use with gas burners, gas appliances and similar use, hereafter referred to as 'valves'. The European Standard DIN EN 16304 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 100 for use with one or more fuel gases in accordance with EN 437. The European Standard DIN EN 16304 applies for electrically operated valves and valves actuated by fluids where the control valves for these fluids are actuated electrically, but not to any external electrical devices for switching the control signal or actuating energy. This European Standard is also applicable for valves fitted with open position indicator switches.
