| BSI | 2013 | 34 |
This European Standard 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’.
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 100 for use with one or more fuel gases in accordance with EN 437:2003+A1:2009;
-
electrically operated valves;
-
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;
-
valves fitted with open position indicator switches.
NOTE Provisions for final product inspection and testing by the manufacturer are not specified.
